Did anyone’s self esteem hugely plummet after giving birth? Any advice on how to feel better?

I’m a year and half postpartum so it’s not the crazy hormones affecting me. I just am suffering from pretty severe self esteem and body image issues. I see women joking about getting saggy or being proud of scars / stretch marks but that’s not the way I feel at all.

I’ve always had some body image issues but could still feel attractive. After giving birth that’s completely gone. It’s not about weight gain so losing weight won’t help. I don’t know how to accept myself as I am. I feel disgusting.

Everything else in my life are pretty good and my baby is absolutely incredible. It’s the main thing affecting my happiness day to day. I don’t know how to break out of it. It kills me when I look in the mirror and realize this is the body I’ll have to stay in forever.
