I want to gain my weight back ... help me !

Abby

So I had my son almost 2 years ago I got real big and I left the hospital at 210 lbs. (my original weight was 148lbs) so after I came home I got the mirena iud and idk if it’s my birth control or if something else is wrong cause I dropped from 210 to 134lbs and at first I was happy but I miss my curves I’m normally a size 8 but now I’m a 6

And Im just not happy but I can’t gain weight no matter how much I eat or wat I eat I just want to gain 10lbs I can’t look at myself right now cuz I look like I’m sick and it’s making me depressed which I don’t think is helping me either😢
