What is something you dislike about yourself?

Something I dislike about myself is that when I am mad, and some one says something mean to me or looks at me the wrong way, or if I take it the wrong way, I will say something to them and make a big deal out of it. I let little things bother me and sometimes the little things make me so but so mad. I hate it when I do something wrong because I didn't think before I did it and I then afterwards I regret it. I dislike that sometimes I can really be mean to people for no reason.
