I, myself, have also been diagnosed with bipolar disorder, and things were very stressful after a very problematic and expensive pregnancy and delivery, unemployment issues, a move, etc. I have a good friend that is entirely holistic in everything and I tried EVERYTHING she could recommend. I went through acupuncture, acupressure, the gamit of vitamins, diet changes, etc. Unfortunately, I didn't find success in any of those things and continued to slide.
Eventually, I gave in and am now on a combination of two prescriptions. I am finally "normal." I just got tired of fighting it. I got to the point that I decided my son needed a mommy that could take care of him. I couldn't stand the thought of him looking back and having my current state being his memory of me. I know medications aren't the answer for everyone, so if you find anything else that does work, I'd love to know about it. But, in the mean time, I do love that I am again able to attend social events, go weeks without crying, and I leave the house :) I play with my son. I get exercise. I'm happy and pleasant. I went a long, long time without being able to say any of those things. Good luck. Again, let me know if you find any alternatives. I'd love to try them. In the mean time, you have my empathy. I'm sorry I don't have more answers.
