I can relate to what you are experiencing. I went from anorexia & in an eating disorders treatment center for it.....to weighing way too much....more than I had ever weighed in my life. When my migraine pain got under control, I could start exercising again & my weight was coming off slowly......then a trauma hit & anorexia hit again & I ended up in the hospital looking like a skeleton which was something I didn't want to look like....but the stress made it impossible for me to eat.

Now, I find that I will buy some unhealthy foods....crackers, chips, eat french fries. I find that as soon as I cut out snack food, my weight comes right back down to the healthy weight that I want it to be at. I personally can accept weighing a few pounds over the point where I am considered to be under weight.....& am willing to fluctuate around that weight. I know you can get back to controlling your weight to that point also. Know it feels horrible when that higher weight becomes known & you know you can't stand to weigh that much.

Also don't forget......exercising causes your muscles to develop....& muscles weigh more than fat.....so some of that weight is your muscles.

I am sure you can figure out the right combination of food & exercise in order to get yourself to your ideal weight. Several dozen pounds is easy to loose without restricting, or purging.
