I feel dirty

I make mistakes everyday and I frequently end up being an incovenience , its not on purpose I dont want to , but I have a poor judgement of things , I was always different and Ive been isolated for a while , wich made my mind slow . I feel like those cartoon characters that mess with everything with one touch .What I want to do is so simple , I just want to be useful and a good person but I still mess up somehow .Bad people need to do a little work to mess with things , but I mess up even trying to do things right . My poor judgement of things and surroundings made me do mistakes wich I feel ashamed , I feel like im not a good person ,
