You summarized 2012 for me. I had about 12 different partners as I shifted between moods. During mania, it was nail as much as I could (horniness seems to explode during this time as well). During depression, it was because I needed love. Looking back, I regret because I actually ruined an opportunity at a relationship because I slept a mutual friend. Neither has spoken to me since. Historically I believe I can identify ending a relationship around when a mood swing happens. Kudos for anyone that keeps their relationship during these trying times.

Keep writing and talking to get these feelings out. Keep your partners legal and always be safe. It's fine to regret a poor decision and rightfully we all should. If anything we can remind ourselves when the next opportunity presents itself how the last time made us feel. Take care!
