Well, I can't answer all your questions, but some I might be able to help with.
It's been 5 years since I've been seriously bulimic (puking regularly due to eating issues). It gets easier to resist but so far the feeling hasn't completely gone away. I still pay attention to where all the bathrooms are and I still want to puke after a big or unhealthy meal. Also I was anorexic before that, and I know what you mean about feeling better anorexic than when you are bulimic. I gained a lot of weight while I was bulimic. I did manage to lose the weight through diet and exercise (1000-1200 calories a day is what I ate) so there is hope of losing the weight but it is really challenging to diet without going back to an ED. I still can't trust myself when I look in the mirror. I'm a size 4 to 6 and I still look in the mirror and all I see is fat, even if people say I'm thin. I try to remind myself that I can't trust my brain and rely on others and the numbers on the scale (although numbers on the scale don't measure health it's closer to healthy than my opinion.)
My face has always been slightly chubby, so I really don't know if your face changes from this. Also, I have always had my period and if you use to and still haven't you might want to see a doctor about that (just my advice).

I hope that helps some. I quit mostly on my own too, I had a counselor but I never talked about it with them until I had started healing on my own.

It's really good that you know you have a problem and are trying to fix it. I'm proud of you.

I wish you the best of luck. Know that you can always come on here and talk and share and get advice.
