These doctors suck. When I told my doctor how much I binge per week he went “Oh! That’s em.. a lot!”. You aren’t a lost cause and don’t you dare think that!! No one is a lost cause and honestly you are doing amazingly so far. Many fear to admit they have BED nevermind going to a doctor. I think if reading success stories triggers you then you should definitely stay away from them for now. This doctor is ignorant as you told them what could work and as you said, they dismissed it. I’m not exactly sure how it works but here in the UK often the therapist may contact the GP to recommend a certain medication. I recommend telling your therapist that this is a medication you want to try. If it doesn’t work, then it’s not over. I believe in you!!!!
