Well, think about it this way: what's the worst that could happen if you discuss this with him?
I obviously don't fully know what you're going through and I know it's got to be hard, but even if the absolute worst case happens where he sends you to back to IP, you'll be getting the help you need and deserve. But if he doesn't think you need IP, maybe you'll get some great coping suggestions?
My point is: no, he himself can't change how you're feeling, but he CAN help you get the treatment you need and deserve so that you CAN feel better and things CAN change for you. I hope that makes sense.
