Gp diagnosed me with bipolar and ocd. waiting on specialist and med. til then, how do i handle confessing things im not sure even happened or the past?

Glad you will be: seeing a specialist. Frankly, I would not confess to something if have absolutely no recall for it or don't know if you are responsible. Why not wait until you are stable on medications and working with a good therapist. Then you can make the decision to make amends and to come clean about things which you are responsible for. Be well.
