@jesyka, I agree with @Itearor.
Don’t think you are not suitable for anybody. This is impossible. There are many people you can fit in with and they fit in with you.
It’s our mind, our insecurities and our own issues the one that make us think like that.
Because they are kind of barriers we have to go through every single day.

I related having some specific issues as anxiety or depression and some personality characteristics as insecurities, shyness, introversion with a lower probability to meet and have relations with people and it was for a reason. Our anxiety is our worst enemy and as soon as it gets triggered, somehow it doesn’t let us being ourselves and when this not being able to show ourselves up as we are and feel relaxed in social situations occurs, it feeds our negative thoughts and triggers anxiety even more and so forth. So, there will probably a tendency to withdraw. Therefore, less probabilities to maintain connections.

Anyway, I see each case as different. Some people handle their anxiety pretty well and have willpower enough to enlarge more and more their comfort zone. I do really admire them so much.

It seems to me this is your case. You even took the initiative to do things with your friends.
Do they correspond you? From what you tell us and what your guts tell you, they don’t. But, it’s not necessarily anybody’s fault. It’s a matter of fitting in, chemistry...

How are the things going now in this matter? Did they contact you?
