Can you write down verbatim what you wrote in your first post and see that he gets it in letter form so he can read and digest some of your thoughts? Five minutes was not enough time to get across to him the things you are thinking. You are not a fraud. You need help. If he doesn’t believe you, please find another psychiatrist who will take you seriously. I’m sorry you are struggling this way and hope you get the help you need. Sending big hugs that you feel better soon.
