when in doubt, don't decide. Search some help to find your path again. It can be help from people you know, but also from a terapist. They can help you to find a way to control yourself when you are feeling bad again.
the problem is you don't know if the one you are on is one that has unknown side effects. but for me just keeping up certain activities and avoiding some is starting to work, avoiding stressors and getting help when i can't avoid them
