i need answers to my angry, possessiveness, and urges

I need answers to my anger, possessiveness, and urges. I am angry all the time. I push people away so much that I actually blow up on people now because they ask me how my day is or was. I have a possessiveness to someone who is not even mine. I have these urges to hurt someone really bad. I want to see them beg for me to stop hurting. I want to hear their agonizing pained-filled voices. What is wrong with me?
