I am Panicking Here or Why The Hell Can't I Sleep?

I am in a panic mode here. I can't sleep. I'm on the right med now so the physical problem I was having is gone.... why then? I can't sit and focus.... There were a few times when a dream started to come but I bounced right out of it. I looked on the net for some ideas and tried a few: warm milk, relaxing sounds, turning clocks around, having a lights turned off (including LED's) I don't know what the matter is.... Maybe I'll never get to sleep again... my body won't be able to take much more of this... in class I've managed to dose off for a bit... but not in bed at home... It's gotten to the point where I micht have to call Tyler and Carrie for some "stuff" to see if that'l help. I want to make it a last resort though and it's probably not the best idea to be smoking pot with mono.... Seriously.... I JUST WANT TO FUCKING SLEEP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
