Hello, I'm almost 32 yo and still haven't a relationship with a girl,this makes me feel so awkward,always beenlonely,shy, not much talkative, not attractive and struggling with social anxiety,fear of rejection,i hate social media,issues with self confidence and low esteem. I can't control emotions.
Take baby steps. Social anxiety can be managed if not "healed". Go out, and just try to enjoy yourself. All you have to do is maybe walk down the street, listen to music on a pair of earbuds, and say hello to most if not all people that pass by. Woman, man, child. It can be scary. But a hello means almost nothing to anybody other than "Oh, maybe this person is open." Depending on the country you're from, some might be open to different things. Americans are seemingly more open to small talk rather than a quick "hello". Europeans are more into a passerby "hello" rather than small chit-chat. The average persons are just like you, shy and possibly anxious. There will be some that probably won't say hello back, but maybe they're shy? The average person isn't hostile. They aren't out to get you or to intentionally make you feel even more anxious (they don't even know you are!). So, baby steps. Emotions fluctuate, so some days will be easier than others. Maybe one day you'll feel good enough to talk up someone about something you enjoy because maybe they're browsing your favorite games at a store or something similar?
Why do you hate media? Do you feel that you aren't permitted to use it because you "aren't good enough"? People who are exponentially worse than you use it. Why can't you? If you don't hate social media for this reason, then is it because you just hate the narcissists on there? Personally, I don't like social media, either. It's a big waste of time, especially the browsing part. But there is an appeal to it. You can talk to people on it, anonymously or not. You can spread the word, create motivation outlets for some, or just talk about your feelings to others you know or don't know. Instead of staring at the people who are attractive or have a huge following and hating them for their achievement, think rather how they got there. And don't lie to yourself or make up information. They're a YouTuber like Jacksepticeye? They probably spend hours editing, days contemplating, enjoying the filming, and looking for something to do. Even the fun things require a little work. If you're lucky, the work IS the fun thing. Instagram model? Yes, being born attractive is not in your control, but everyone has intelligence of sorts. Intelligence isn't one fixed thing, there are various kinds. These Instagram models might say lots of stupid and make you wonder how they got there, but they know how to dress, they know how to apply makeup and/or stylize hair. They can pick colors, learned what people like and what visuals brains appeal to most. Not all of this is magically obtained by genetics or luck, some are developed after starting Instagram modeling, some are learned during other hobbies as a child/other times of life.
I still can't believe how I'm still a virgin when other dudes i know had girlfriends from school years and university years, this is madness and sadness, also I'm overweight and that doesn't help my image and my mood. I'm completely lost,i struggle much in work environment as people around me see me somehow weird.
You can't believe it? You're saying that other guys were in the exact boat as you are/were? Overweight, no social experience and whatnot? Or did they have different lives, different experiences? If there were like you, they did something to overcome themselves. Not in a day, not in a week. It's easy to blame yourself for something because you can't do it. It's self-sabotage. If you get angry because people tell you to stop having reasons not to do things, then there is definitely something that needs to be self-evaluated on your part. Everyone has reasons not to do certain things, usual ones would be drinking alcohol or smoke, but not everyone has reasons to not do everything. Time is irrelevant, especially the past. If you use the past as a reason why you can't do something in the present, then you will never do it in the future. Forget those guys, forget that they have what they want (or maybe they mistakes, who knows? Who cares? What matters is YOU AND YOUR DESIRES THAT NEED TO BE APPROPRIATELY ACHIEVED). Comparing an orange to an apple, and then calling the orange a failure because it's not an apple, is plain stupidity. The orange, you, have certain characters of it's own, with purposes different from the apple's. Almost everybody wants a relationship, like most fruits eventually get eaten, but you need to be ripe first. Grow yourself.
Lack of friendships,chronic loneliness,no much support from parents/family enviroment,lack of life experiences such as having fun with friends out,flirting/dating with women,going vacations to relax,boring at job with small salary,no motivation,no escape from nothingness,emptyness.
The easiest place to start for support is the internet. And you're here. Maybe not in the right place per your replies to others, but browse around and you'll find someone willing to support you. Discord for example has many communities you can join. Flirting with women is a lofty goal, one you will definitely not get to from level 0. Communication is a human thing, so flirting could come natural once your confidence is high enough. Others have explained already, and many more via research, explained how to get to your goals. So just set aside your desire for a relationship. You want it now, but realize your brain wants EVERYTHING NOW. You're never too old or too young to start something. The only time it's too late is when you're dead.
There is always an escape. Sometimes even the nothingness is an escape, just sitting there, thinking about how terrible you are. Play games, find shows to watch, get into anime perhaps or a niche sport like bow shooting. Take on writing, drawing, digital art, making reviews, uploading progress videos to YouTube for others to relate to you. There will be people who will hate you, but remember, they're probably in the same spot that you are. And those people at work who see you as weird? It's just because you aren't like them. If something is different, of course it's unusual. That in itself is not a bad thing. You can still be a shy/quiet guy with confidence. People are naturally scared of things they don't know or understand. Once you can communicate with people about the way you are, it might just alleviate some of the pressure.
From the replies I'm getting, you're seeking comfort, maybe even have people tell you that it's okay the way you are. Honestly, it comes down to your OWN opinion. If you are okay with the way you are, then everything is fine. However you aren't. What your conscious mind wants is to be appealing, lose weight and be confident. What you don't realize is that your brain is fighting you on this, and it's seeping into your conscious mind, making you want to hang on to the way you are, and say that the world should bend around you. The brain itself doesn't care about you. The brain just wants to indulge itself, and self-loathing is another one of these self-indulging things, believe it or not. Saying that you are bad in being in a bad state is an easy way out for your brain to say that you're right, and then it boosts it's egotistical indulgence. You need to fight this. You won't have motivation most of the time, that's why you need to create it. All you need are the tools - your body, knowledge, and an idea. Make a simple goal, and stick to it. During the first days, you WILL feel lazy and disinterested. You brain will want to go back to the lackluster, effortless boost that was going on. The ball needs to start rolling if it's going to get anywhere. Your life won't drastically improve by one simple task, but it will feel damn good at least trying to get something accomplished like a chapter of a story written, having general conversation online or saying "hello". Your brain will try to blanket these with anxiety or "What-ifs". Just forget them, and ignore them, and give yourself a pat on the back.
I've thrown out many ideas towards you to think about and manipulate in your mind for your own benefits, relevant or not, positive or negative. It's up to you on how you want to use it. You already know what you need to do. You might also know what you could already do.
My message has many errors and topic run-offs (or segments in inappropriate paragraphs), but I hope some of it will be helpful to someone. It's not professionally done, but sometimes amateur solutions work. I would assume, having dealt with complex issues solved by simplicity.
But i don't understand this unfriendly,indifferent behavior over here,it's simply dissapointing.
