As someone who also had an eating 'distress' (but really an ED for 12 years) I would try to speak to your t, before you do the damage I have done to myself.

My t didn't get 'it' as it isn't her specially, so I sent her a book in the post about it, which was the best thing I could ever do. She read out chapters with me and got a greater understanding which really helped.

Please don't give up on yourself. Perhaps you need to think about what has triggered it recently to.
