My pdoc suggested tracking my moods.....does anyone else do this and is it helpful?

Ive read on a couple bp sites that If you feel the start of a depressive episodes you should seek medical attention to prevent si/sh/suicide......is that necessary?

Ive also read that if one becomes manic that depression usually follows.....should I tell gp if I become manic?

I also dont know how to ask my hubby to check out a couple bp sites .
Maybe I jshould just try myself to explain....or has anyones T's talked to spouses about bp diagnosis?

Id appreciate any feedback
