I started HRT as an adult and was advised that having an eating disorder that I was not on the path to recovery from would complicate things for my body and risk negatively affecting my health which I can understand being a concern of my GP...a bunch of things parallel to this type of behaviour I struggled with for years after(some worse than before) and my GP was still helpful with me. She did not use my HRT as a carrot on a stick for me to recover...my HRT being effective was the carrot on the stick I needed to recover.

I get what you are saying but I’ve also had a psychiatrist avoid medicating me because of active drug addiction(I’m aware the difference) and while I don’t think gatekeeping is helpful we probably should keep in mind that these people do have a duty of care
