Try not to think of yourself as low or high functioning. It comes and goes.

Remember to her the “real” you was/is the hypomanic one so “normal” you looks depressed. I would still talk to your dr just incase she sees your mood swings before you do. If she is your “caretaker” when you're really sick make a contract for behavior that needs immediate attention. Give it to her, your therapist and your Dr. That way she has a clear cut “Call the therapist now!” My husband and I have made a deal that we will not hospitalized each other but we can sure as hell tell on each other. You may want to give her your dr.s and therapists # so if need be she can tell on you but not get any information about you. She does want you to talk about your issues as long as they're not BP related.

These are things you talk to your therapist or psychcentral about not your sister. Honestly, for dating I would not say your bipolar until it comes to living together seriousness.
