Why can I not stop crying when I do something wrong?

I would say that the first thing you should do is talk to your parents or your guidance counselor about what has been bothering you. Being thirteen can be really hard because you are going through a lot of biochemical changes. You might be a little misunderstood because it sounds like you are gifted and emotionally sensitive, which is just who you are. I used to cry a lot in school and get teased but what I learned is that there is something about me that is special and people could see it and chances are people see the same thing in you. Don't be discouraged! ;)
