I have 5 days to go before major surgery - I'm having a total knee replacement. I'll have to use a walker for 6 weeks and a cane after that. It's so important to keep a positive attitude - an "I can do it" attitude, so that I can endure the pain of surgery and learn to walk again. I am all alone with no one to help or support me. My 2 daughters don't live nearby and their kids are in school, so they can't just take off to be with me.

I was hypomanic this summer. It's all gone. I can feel myself sliding into the pit of depression. The black dogs are coming for me.

If I deliberately sleep only 2 hours a night from now until Thursday, can I make the hypomania come back?
