When I read your first posts in this thread, I didn't initially understand why telling your treatment team about things like eating or sleeping would be an issue, as I don't consider those things to be very personal or embarrassing (in contrast to things like hypersexuality or irritability).

But in light of your last posts, it does make sense. It sounds like you've had your trust betrayed too often. If it were me, I would start there. Tell my treatment team about those trust issues and try to work on that first. Then the other stuff might follow. The first thing for me would be to work towards a collaborative treatment, rather than simply being subjected to whatever your treatment team decides. You could try to gauge whether they're open to that sort of relationship.
