In my case, I found as I got older, I had longer and deeper depressions (starting about 38ish). The worst episode I had was at 49. (Terrible mixed for 3 months). But I've also been doing well quite a bit too. I am 56 now. In my younger years (starting around 20) there was a lot of hypomania. (I was changing jobs and living locations like socks, lol). I think I'm more patient now. Some, anyway
I really do think it's a case by case situation.
