Feeling frustrated and have no hopes

Hello ,
Recently Im having a lot of trouble which made me hopeless and stressed out , whats Happening is that I’m always forgetting things, careless about everything, I lose things suddenly, recently, I lost my wallet , i have missed the exam registration time even though I lost it last month (it happens once every month) , I lost my headphones in the bus, ... etc there are thousand of things that I lost .in fact things are getting unbelievabe like I don’t understand how could I easily lose all these things . I feel im careless about everything, for instance i have missed many important appointments this month
One of the things I noticed, when Im doing something, I tend to do another thing at the same time , my attention can’t stay focused on one thing ,
I also feel neglected by everyone, like im an unwanted person in addition , when I’m feeling frustrated i can’t find anyone who could understand me
Even when I talk to girls , they never give me that attention, it always feels like im interested to talk with them , for example when I use tinder ,a girl would send me few messages then she disappears .
I desperately try to talk with girls , nevertheless they don’t have any interest in me.
A short story I would like to telI I have met a girl few days ago , she didn’t give me any attention when I was meeting her , she was using whatsapp all the time , so we went to a restaurant, when we finished she asked me to pay the bill then she never showed up again .
Moreover, I tend to avoid meeting people , because i get the impression that they are not interested in me , it sounds strange , for example: my girl roommates who im living with , they rarely talk to me , whenever I try to approach them they don’t seem interested, ironically even the roommates which I shared the appartement with , were exactly the same , despite the fact that they talk with each other but not me.
Another thing which makes me very frustrated and shocked is that I have invested in crypto currency , at first things were going fine , prices were stable however after few weeks , the prices went down, and now they their value is much lower than the price I payed. Im confused, I don’t know what to do because I don’t know if they will rise again . The problem is that I have invested with almost everything I have and I don’t know what to do now.

Sometimes I think in a way to end my life , because no matter how I try , things go worse everyday
I need help otherwise things would go much worse...
