I hate the depression that comes after a manic episode

I was on top of the world for 3 weeks, now I just want to cry and I feel my body starting to be numb. I have an appointment with my psychiatrist in a week, but I don't even know if I would be able to go as it's far from my house. My psychiatrist prescribed me something to sleep while I was manic, now I sleep from 11PM to 1PM and during the day I find myself trying to sleep to escape reality. My house is a mess and I don't have the strength to clean it up. I hate this illness.
