Nervous breakdown

I think I'm on the brink of one. I can't be certain, because I've never had one before, but it's not looking good. Last night, I went to sleep with this twitch in my left shoulder. When I woke up, it was still there, and has been coming and going all day. I also found myself trying to burrow a hole into the wall with my head as I tried to get to sleep. And it sounded like there were sirens going off in my head. I want to talk to my mum about it, but she'll just cry, and I'm too stubborn to get psychiatric help, which I think I quite badly need now. Just look how many blog entries I've made today: two! Crazy.
