help???

So I'm feeling pretty good today on account I have to attend school which isn't so bad really. I just let things get to me and the more I do that the more things appear to be bad.  It really depends on me to want to help myself. I need a few different opinions though. I can't evaulate myself and figure out whats wrong, so I get on here and ask for advice. Anyways, I'm just sick of people calling me names and thinking they know who I am. I'm so fed up with how cruel this world can be and how easy I let people bring me down..I have poor confidence, I let people run their evilness in my blood and then it makes me break down in anger and in depression. I run away from my problems a lot, I have rage, I say things to people I don't mean when I'm angry, and it usually hurts their feelings, sometimes I bring people down with me when I'm feeling horrible and really I can't say why because I don't know.I've tried many counciling methods and nothing is working. I need advice...On a good note I have been working out pretty much everyday minus weekends. I'm struggling in school right now but I'll get through it, I'll walk this year.
