Tortoise is right, if you can control the mania, it makes the depressions less severe.
However i have found that i do better living with a mild hypomania, that helps me deal with the depression. That way i dont have to deal with meds. But that is 4 years of work to get to this point.
Reducing as much stress in your life, both external and internal will do wonders.
When im depressed, i tend to listen to music, and love up my puppy. Plus i try to do some common household chores to just feel like im not a complete waste. LOL LOL LOL
