You're going to find in life (as you live longer), that people don't particularly enjoy
hearing all the negative about life. They appreciate the positive far more and respond to that in a more positive way, too.

Whatever you do is your choice, of course, and you choose the risks you take when you bring out the fact that you have bipolar illness and that you made mistakes because you were bipolar, not because of some other rational things that might have been part of the reason for the mistakes; i.e.., the jealousy, etc. (Those are not specific emotions relative to bipolar illness alone; they are universally experienced emotions.)

I just wouldn't be so frank with all my personal data with everyone. One of the reasons you're posting here is that you prefer privacy. Why open it to your friend unless you are fully knowledgeable about her understanding of bipolar illness and the mood swings that occur and the chemical imbalance, etc.?

Keeping a friendship is partly in maintaining a positive and helpful attitude toward the friend and showing compassion for her feelings--a thing that is difficult for a bipolar when one is in a "mood". Unless you know her well enough to be sure that you aren't opening something that may distance yourself with her friendship, I'd leave it alone, except to blame the jealousy, etc., on teen-age years.

Just my view on it.
