Would you say something is wrong with me?

Sadly i feel really odd. I think im becoming paranoid....

I cant stand to have people touch me lately, the mentioning of someone even touching me puts me in a horrid mood. And i rarely eat nowadays. I skip lunch at school (im in my teens) because im never hungry.

I seem to be always angry, and my moods are always changing, usually randomly with no given reason.

I have been getting very poor sleep, since i can never seem to stay awake during the day, and it takes forever to fall asleep at night.

I want to be alone, all the time, always alone, and when people try to get me to interact with them, or talk to them, or they ask me questions i tend to snap answers back, give an attitude, and become enraged.

And i cant make myself motivated to complete anything, whether its my artwork, doing schoolwork, talking to friends, or helping someone plan something. I just have no mental energy or spirit.

No clue why im acting like this, and i dont need "oh its your teenage hormones hun, dont worry" because i get enough of that crap from my friends and family. I doubt lack of sleep, always being tired, and inability to have fun and becoming a loner is what normal teenagers do. since all of my friends and everyone i know my age are peppy and happy.
