feeling terrible

feeling so depressed not sure why, so tired dont understand why my leg is all swollen. I hurt it a few weeks ago, when i pinned it dont understand why it took all this time to swell up? I stayed in bed for most of the day with it up. It looks a tad better but not much, its still a little sore. ate a banana and candy bar today i know thats not a lot but its better than nothing. really struggling today with food stuff, it was bound to happen cause i ate things that i usually don't. sometimes i get so scared though cause part of me doesnt care and doesnt want to eat, just wants to get small, i feel like a fat cow today. How i wish i didnt have to deal with anything and could stay in my house forever. I am tired. Sick of my drama that I cause to my own self, this is all my fault. everything is. The past is the past, it is my fault that i let it effect me like this. There is nothing i can do about the past, I let it haunt me, i give it the power it has over me; I have no one to blame for my current circumstance but me. How is it that i am so weak as to let myself give in to all that crap? I am a mess and its all my fault. all the ppl that hurt me in the past are just fine, it doesnt bother them in the slightest, they live their life. no nightmares, body stuf and flashbacks. I need to be stronger. I am not the past but i let it control me. Talking about things doesnt change them. why can't i just let it go? see i am not strong, i am weak. your thoughts control how you feel so therefore its my thoughts that have me in this hell. I should just stop everything. stop trying and hoping. I am not strong enough, i deserve to feel like crap cause thats what i do to myself they are my thoughts; everyone says put the past in the past dont dwell on it, so why dont I cause i am weak thats why enough enough of it all there is no hope for me. I can't make it stop, i can't change nothing. its my fault all of it every single thing because I am not little anymore have no one to blame but me for this pain;
