I'm serial-killer crazy

Theres something about me...something weird. I've always thought I was normal, yet in the back of my head I kinda had a feeling that somethings aren't right. I used to have these "intuitions" when i was a child. I could "feel" things, bad things. Things little kids shouldn't be feeling. Kinda like I could feel that someone was in trouble. My parents even told stories about me walking into their room. One instance was I walked in their room and just stood at the foot of their bed, my mom woke up and asked me what was wrong. All I said was something bad was gonna happen, I didn't know what, but something bad. Something did end up happening but my parents never really told me and I was so young. Thats all passed now, but now I have these different....senses, idk what the hell to call them but i am sure no one else feels these things.

Pretty sure I'm bi-polar. One day I'll be happy, making jokes, just being a happy guy. I'l clean the house, go skateboard for a few hours, watch some tv. Have a really good day. Then the next day, something small like an insult or even nothing at all, just thinking about my self-esteem level and I'll be the most depressed person ever. I'm in a mood like that right now. Something told me that friends are worthless, and that theres a reason why I don't have any. Right now, when I go to class, I make no eye contact with people or talk to any people I know. People will say hi, and I'l just glare at them not wanting to say anything. I'm getting in trouble a lot too, with family and professors. Getting kicked out of a lot of classes and I'm not motivated to graduate. It seems all pointless to me, which isn't like me at all.

I can read people...really well. To the point where I can feel their pain and their depression. My pregnant sister was sad one night, because the father of her baby wouldn't come to our sister's dinner party. She was sad, mopey, really really depressed about him not being there. I couldn't look at her, especially in her eyes. Like instead of her, it was me that wanted him there. I had to leave the room to regain control of myself. I can't stand seeing people in pain, because I feel exactly what they feel and it hurts too much.

The weirdest part of me is when I become sensitive to sounds and my own thoughts. It's so hard to explain because it doesn't make sense. Sounds bother me, my thoughts take don't seem like they belong to me. Like they're someone else's, yet I know i'm thinking them. Like I want it all to stop, as if their is a busy train station in my head.... but i'm not hearing any noises. Thats the best description I can make. It doesn't make any sense to me.

These things don't happen when I'm high, and i'm not taking any medication...but maybe I should be. I need help.
