As I know it goes away in a week or so, I don't get worried or overthink it, as I know it will pass. During mania I don't buy expensive things, start big projects, make life decisions, or do anything that may be tainted by my over optimism.

When I'm feeling low, just try to exercise, eat healthy, think positive, follow all my routines.

Basically I try to keep a rational mindset that I keep separate from my current state, and try to analyze the situation as a neutral third party would. This is a useful technique regardless but especially effective when I feel off.

Thanks for your response! It sounds somewhat similar to the mechanism I use albeit mine has a bit of a weird twist to it .

It sounds strange but my goto method is visualising my negative sate in my head as an "alter ego" of me but more messed up (think hobo + zombie-ish) and trying to either talk rationally to this person. Sometimes I get a good discussion out of it or sometimes it results in a fist fight. Either way, the outcome for me is I get closure out of it.

I did say it was strange. :)
