Trouble with weight gain!

A🌟R
I've been suffering from an eating disorder for a little over two years now. However, ever since I've been in recovery I've noticed that I've put on A LOT of weight... I'm actually considered overweight by my BMI. The weight just won't go away! I'm eating regularly now and I exercise quite a lot, but I seem to be gaining more than anything else. I don't know what to do!! Anyone that can help?!
