I had mania more when I was a teen but now that I'm older it seems I've kept myself in my depressive states to avoid anymore manic bad decisions. 

It's just a theory but I know when I feel myself getting happy I get nervous. It's a little because I don't want to feel worse when it goes away, but also because I am aware of how manic I can get when I'm excited about something.

If I have a hobby or new relationship I'm passionate about it affects my sleep and causes more mania..

Anyone else also have this issue..
Any potential solutions..?
