I hope you are feeling better. Once you find a trigger it make it easier to work through it. Just take your time and go back at it slowly until you feel comfortable again. Right now it may feel like you can't do anything right but when you cycle, especially rapid, it makes it feel that way because it feels confusing.
Have you been able to read any of the Bipolar Survival Guild and if so is it helping any? Mood charting is a good way to also find your triggers. I haven't done that in a while but my new therapist wants me to so we can see if there are things that may be triggers me.
"It is not easy to live life sometimes and face the world with a smile when you're crying inside. It takes a lot of courage to reach down inside yourself, hold on to that strength that's still there, and know that tomorrow is a new day with new possibilities. But if you can hold on long enough to see this through, you'll come out a new person - stonger, with more understanding and with new pride in yourself from knowing you made it" Kathy Obara
