Teenage angst or more?

I'm 16. I've been having thoughts of screaming as loud as I can and beating the life out of people. When I walk down the hallways I'm scared someone walking past with their binder and accidentally gouging my eye out. I cry at inappropriate times. I just tear when I'm angry or jittery, and I laugh when I hear about people's misfortunes. I'm not quite sure why. I know it is wrong, but I can't help it. I know every teen thinks they're unique and they've been through "traumatic" situations, but I think I really have. I used to get beat up a lot by the kids in the neighborhood, and they would do other things. I lash out at my current boyfriend when he gets too touchy-feely. I get annoyed when he tells me he loves me. I hate liars. I hate when he tells me I'm pretty or skinny. It pisses me off so badly. I feel like he's just lying to me to make me like him more. I do like him. He's a marvelous person, but I just get so fed up for the smallest things. I hear screaming in my head when I'm upset. It used to be a man, but now it sounds like a woman being smothered with a pillow. I used to have a family psych, but we quit going after we went to so many. Most blamed me, but they would never let me talk out what I needed to. They told me to listen to my parents.
