Hi there! I'm officially diagnosed with BP2 as well, although I think I might be closer to BP1. Mood stabilizers have changed my life for the better, although if you think that you'd prefer not to medicate (after all, there are serious side effects to consider), then feel free not to! I was against medication for the longest time (and for good reason), especially since it took a while to find a combo that helped while minimizing side effects.

Coping strategies for managing BP2 without medication (or a low dose of meds):
* DBT/CBT: there are plenty of workbooks. You could see if your local library stocks them, browse through a few, and buy the one you find most tailored to your needs.
* Counseling -- do you have access to a therapist/psychologist, or is this out of your budget too?
* Natural "medication": fish oil (omega-3 fatty acids) and chamomile tea help me. Some people recommend vitamin B supplements, as well as vitamin D (if you're deficient in this vitamin).
* Balanced diet: cutting back on alcohol, processed grains, refined sugars, greasy foods -- these are general keys to better health too.
* Exercise: I love to swim, especially during the summer. Taking walks, yoga, etc. are good too. Do what you enjoy.
* Meditation. This was really, really helpful for me. It's tough. I fall asleep constantly. Still helpful.
* Aromatherapy: lavender helps me relax while feeling more alert (I have anxiety issues, and lavender helps settle them).

I'd love to talk about this more if you like. Good luck.
