Fuck off

I've spent the last few days still fed up. I'm annoyed at myself for letting one thing affect how i felt so much.

Why is it that once you get something in your head it just wont seem to go away. Feelings of guilt, resentment and sadness
I'm sick to death of feeling crap. I never did anything to deserve this. I've always tried to be a nice person even to people that haven't been nice to me.
So why is it I cant just let go? Is it my need to try and make people happy? My need to make people like me?
Whatever it is I really want it to just fuck off and leave me alone. Its causing me to be physically ill, i had to go to the doctors this morning for antibiotics. I've lost 4lbs in as many days. I cant sleep and I cant eat. Just get off my back. So tomorrow I'm going to look at a new kind of therapy to try and sort this out once and for all. Im sick of this ruling my life.
