I feel like a burden for all the people around me (both financially and emotionally).. because of me, my parents have to spend a lot of money (for therapy, meds, ecc.) and it makes me feel guilty. And I get the feeling they're not happy about this. And it's all my fault because I am the one who's feeling this way..

Same thing could apply for my friends here at PC.
I try my best to be helpful and supportive, but I feel like that's just not enough and that I'm useless most of the time..
