Well you didn't stress me
I know that you said you can't take advise but I'll give it anyway. I'm pushy like that.
Negativity isn't bad to be around, that's new age mysticism crap. Most people I've ever met are the glass is half empty kind of people. Hell I know I am. Maybe its a bi product of the industrial age or maybe our monkey ancestors saw the cup as half empty because if they didn't refill it in a drought they died.
Whatever the case get out there and meet some people. If you feel like a burden ask, all to often we perceive things that just aren't true. So verify it with someone else. If they do say your a burden f*** em, find someone else.
Hope you feel better soon.
