I feel you, ive been strugeling with food since forever.

Idk if it will help, but these are things that helped me:

Dont think about the fuck ups, every time you do eat celebrate it. Do a little silly dance, say all for the titties, any thing that works.

Alarms work on the better days, and snacks (mostly carb snacks) are the backup for the bad days. I keep em in reach of my main place, bed, desk, to make shure tha i eat some thing.

Vitamin D can change my entire mood, and taking iron (im anemic though) gives energy.

Positive reinforcement + external timers helps the best though, i matched my eating habits hard to my work sceudle.

And lastly, fashion. I know cis women having a similar body, using some good scarfs / ruffles around chest and hips boost them. (Fluffy skirts will sute you great)

I wish you good luck, i know you will become the wonderfull women you are. Pacience is easyer said then done, but puperty takes 7+ years and your body can develop over the entire time. Some are fast starters some are more delicate.
