I have had FAR too many depressive episodes to even begin counting. I get depressed more often than I get (hypo)manic.

I started getting depressed around age 12/13, and now I'm 29. So, I have no idea how many I've had in the past 15+ years. If I look back, some of my depressive episodes lasted months at a time. Even worse, they'd go away after 2-3 months, but then 1-2 months afterwards, I would get depressed again for another 2-3 months. I think the (hypo)manic stuff didn't really happen until age 15.
