I know it is hard but I think you should tell your psychiatrist. You will need to give him all the information so he can help you. He is there for you not against you. He can not make you do anything you don't want to. If it is to the point where someone would intervene than it will come out at one point anyway. It sounds like you want his help so I think you should reach out for it. This is only my opinion obviously and you will have to make your own mind up. Good luck with whatever you decide.
