Diastasis recti 14 months post partum

So I had my second 14 months ago and even though I lost all of the weight and look thin I hate my body.

please don't say "girl you look great" I don't want that. I FEEL like crap about my body I want to fix my stomach I have tried all of the exercises on Pinterest and I'm beginning to think it's hopeless I have a 3-4 finger gap over my belly button

and a 2-3 bellow and above

I do keggals Idk what else to try what helped you guys? am I alone? it's effecting my sex life.
