It really does seem to be an ED of some sort. Especially with your absolute loathing of food, the purging...binge-purge anorexia perhaps? but don't quote me of course. your T will be ten thousand times more reliable...I really think you should tell your T because this sort of thing can spin out of control quickly. Especially since it started years ago, now you can be gradually getting worse but it won't seem "worse" to you because you're more accustomed to it.

And yes, I have gone through this exact same thing actually. I started out eating breakfast, skipping lunch at school (i'm a senior in HS) fruit/veggies after school and then i'd get home from work at 11 or so and binge on whatever I could get. My solution was probably poorly chosen...I decided to go vegan (for moral reasons as well) but that's helped me a lot to curb my binges.
