Why do I mess everything up?

Why do I always mess everything up? 

I'm always doing something wrong. there's never something I'm doing right. too fat, too stupid, too lazy, too much acne, i missed one spot when i was cleaning-- i cry too much, you worry too much- you interrupt people too much (my untreated adhd makes me do it and i never mean to). 

is there anything im doing right? why can i love myself? why doesnt anyone love me? why am i so broken? am i an error that god made? maybe im not supposed to be here?\

i just wish there was something i was doing right. i wish someone said they were proud of me and that they loved me and wanted me around. 

i know this is stuff i should be telling myself. i know i should learn to love myself- but its so.. so hard when everyone around me and fate, and the whole world tells me otherwise. it hurts so much. and it gets worse and worse as time goes by.
