I'm someone who has posted about how self-care strategies have helped my stability a great deal (i.e. exercise, part-time work rather than full-time, therapy, etc.), but in that post -because it wasn't relevant to the OP's question- I don't think I mentioned that all of this wouldn't be enough but for the meds I take for BP. I wouldn't have stability without meds, however, for me, it has taken a combination of self-care (lifestyle changes, whatever you want to call it) and meds.
