I've been mostly out of a depressed state for a couple weeks now....long time for me, but I'm in the same boat. When someone that ticks me off is even in my sight I remove myself because I'll blow up! When the mania spikes I clean, write, punch a mattress, or whatever. Basically, if you're in the mood to do something and you know it's safe and won't harm, do it!
HOPEFULLY this time neither of us will end up in the hospital, lol. [I'm def prone to it]
