(Not too sure how this works, but I was desperately seeking answers)
Hello, I have been told by my friends how I have always been mysterious and rarely open up to them. Personally, I am not comfortable being vulnerable in front of anyone and despise showing that side to anyone. Apart from that I genuinely don't believe that my family or closest friends need to know everything that I am doing. It is not an attempt to stay secretive but I just think it is convenient and way easier.
In this regard my question is: I have been friends with my best friend for 10 years now, the only person who I have such a long and steady friendship. Recently she left to study in the US alone and those months were a little busy for me so I did not talk to her as often as I'd like to. This led to what she called 'accumulated irritation' were she talked about how I always make her feel lonely and unimportant or don't care enough.
In my defense though, I see relationships in my perspective i.e in reverse situation if I would be okay or not. I have patiently and with interest listened to her (in my opinion) silly boy rants even when I myself was going through situations where I was diagnosed with anxiety, my family become bankrupt, etc. I am not saying my problems are bigger but pointing out that even with these things that i don't share I have graciously tried to be there for her always.
Where do I, as someone inept with showing care, show that I do care?
