Can bipolar disorder be messing with my sleep?

i can understand not sleeping, my mind is just too switched on even though i m so exhausted. the way I get to sleep is by taking pills and shaking my head side to side gentle (i know that may sound mad, but it helps calm my mind) I dont think/Know if i m bi-polar or just have an anxiety problem, i ve been told i have depression by doctor so i guess thats all i have but, my GP is thinking of sending me to a psychiatrist . it take me 2-3 hours to get to sleep, i normal sleep 4-6 hours a night. I used to have hypersomeia like you did, i could go 12 hours sleep, looking back it was great, now not sleeping enough is just adding to depression causing more problem. So yeh i think i f you have Bi , it is affecting your sleep. you should see you gp like i m doing, if i had not gone to my doctor, i think i would have ended up crazy :( why can't our stupid brains just let us rest
