I can't stop sleeping. I sleep nearly 12 hours a night but go back to bed for naps about three times during the day outside of work or university. I am having trouble concentrating and despite all the sleep I am utterly exhausted. Still fairly new to the bipolar diagnosis I am guessing this is depression, although fairly mild on the scale of what I have experienced. There have been some times where my thoughts distort and become disturbing so I take extra Zyprexa (Olanzapine) for that, which helps with those symptoms, but I don;t know what to do about the exhaustion. Do I keep sleeping, or should I force myself to get up and stay up even though I struggle to function due to sleepiness? I am scared I am falling back into a deep depression and I want to nip it in the bud now to prevent that. I don't see my pdoc for three weeks. It is making study so difficult I am scared I may have to pull out. I am only doing one unit as it is due to my health so it would hit me hard to have to pull out completely.
