Feeling depressed everyday now

I've gained 65 lbs during my pregnancy, stretch marks on my stomach hips and upper legs. I was so petite pre pregnancy now I'm considered obese. I feel like my body is never going to heal from this. I dont think my husband understands that I'm not just going to bounce back like he sees on social media everyday. He started to follow all these fittness females on instagram who I'll never be able to look like. He chooses to look at them all day everyday, follow their everyday moves like hes in a relationship with them or something. He doesnt understand how shitty it makes me feel. Ive told him how it makes me feel and he doesnt care. He keeps saying I'll bounce back like so and so he sees on social media with 6 pack of abs ect. More like 6 rolls for me. 🤦‍♀️ I cant look in the mirror without crying and having panic attacks. 😭 sometimes I feel like I'd be happier with myself if I was by myself.. i feel so alone that maybe I should just be alone!
