Bipolar is a disorder that does come in episodes.

There are many ways to try and stay stable. One method is taking psych Meds. Working with your Pdoc to fix in on the best combo. Change when it's not helping.

If you understand what mood was pre Psycotic you can work on prevention. Getting help before psychosis is a good idea.
Once I saw my T everyday and my Pdoc once a week. It worked better than in patient in the hospital.
Yes I've had many many Psycotic episodes. Usually when I get the idea to go off my Meds.
