I agree with this so much. I gained 20 kg this year, and I hate the way I look. It's hard to admit it when I always support body positivity, but I honestly just can't wait to lose weight. And it's SO hard, for some mysterious reason I can't put my finger on. The worst part is that my body doesn't feel as fit and healthy as it used to. I'm having complications when I didn't use to have any. This whole weight thing is a struggle. It's definitely quite complex. As long as someone feels good in their skin, I support them.
As for me, I want to lose weight ASAP. (And I didn't gain it from giving birth, I gained it from zero exercise in quarantine and eating too much take out and cakes. Ugh.)
