i recognize alot of self awareness in your post. you seem to have a pretty well rounded understanding of what your highs and lows look like, and what their sources are. this is a crucial part of maintaining balance. balance is what you are seeking here. a good tip is to avoid all these extreme highs. they have a similar effect as an extreme low in that they pull you away from your emotional center and may leave you stranded with only a hair-thin tether to bring you back to the source. i think you are in a good place either way and that continuing to examine yourself, regardless of your other courses of action, is a solid idea.
