Hi there. I can feel you. Even when I end up deciding that I should talk to someone about my issues, it seems like they either underestimate the impact of these issues and are inappropriately light-hearted. I seldom get the kind of attentiveness I hope for when I share my stories. Now that I've tried so many times, I don't want to try and bother my friends anymore.
I actually kind of enjoy this solitude. After all, we all are occupied with our own problems. It is understandable why people always respond to others' ordeal in a passive tone.
However, I believe not all people are that cold-hearted and selfish. You just have to talk to the "right" person. Could you think of one of two friends who are friendly, understanding and you're comfortable talking with? You don't have to worry about bothering them, at least not when you haven't tried yet. (sorry if you have) If they are busy I'm sure they would let you know. That's completely fine and has nothing to do with "you bothering them", it's just that they too need time to deal with their own needs.
It is very kind of you to be considerate even when you're so sad, this is a virtue you should be proud of. :)

I understand what you must be feeling like. I have turned down good jobs to avoid working with people. I am very self conscious and just don't feel acceptable to others, but it's the way I have been treated all of my life. I'm 67 now and I hope you will get the therapy that I wasn't given. It's too late for me but not for you.

I know what you mean. I've gone through that before in small degrees, but now it's just been heightened to the point that now it's becoming truly painful to go through that. I hope that you do what you are able to do, so that you can be free.
