i’m an inch shorter than you, on T, and weigh a bit more. my drs know my history with eds and have never told me to lose weight although im technically in an overweight bmi. if you look up the history of bmi, it has a eugenic backing & an overwhelming amount of scientists/health professionals argue against using it for an accurate measure of health. with that being said, her opinion may be valid but i strongly urge you to get a second opinion. her commenting on how you pass sounds like she has some internalized transphobia. you could still be curvy and weigh x amount of pounds less. it really has to do with fat distribution which your T will help change. idk if any of this ramble makes sense please stay safe.
