Is this even the same person?? I need help

Two months postpartum, January 2017

21 months postpartum, August 2018

35 lbs difference.

I know at the time I hated my body and my pudge but I actually miss it now. Look at how skinny I am. I have NO CURVES. I look like a boy. Idk how to get my curves back without getting a giant belly again. I’ve been eating a lot, working out, and drinking protein shakes but nothing helps. I am happy to be thinner but I wish I was a little bigger than I am now. I feel way too skinny.

I have thought about seeing a doctor because the weight loss kinda happened randomly, I didn’t try to lose so much weight. What are everyone’s thoughts? What else can I do to gain weight? I’d like to be in the middle of these two pictures.

It seems like the more weight I try to gain the more I lose
