Give me a diagnosis please??? What is my condition?

I'm 20 years old and I seem to be scared of the world. I'm very bashful. The only feeling I have are usually jelousy, and rage and that's all i express. i have no desire to interact with others anymore, i have no connection with other people. i'm not fun like i used to be, i've lost all my friends. i'm starting to see people as objects since i've been hurt so much. no motivaiton to do anything anymore. sometimes i like to bring people down to give them a little taste of what i have 2 deal with. what is my problem?
