Sorry to hear this, sinking.

Have you been diagnosed (or self-diagnosed) with a particular eating disorder?

Try not to lose hope. You certainly can recover from this.

Personally, I found that it was a slow process, with lots of relapses (and sudden improvements).

Opening up with your T is bound to make you feel messy, and exposed.

Do they have experience of eating disorders?

It might be worth joining a group with others in the same position.

Anorexia / bulimia are weirdly particular in the ways they get a grip on one's mind.

Big hugs.
