How do you get over insecurities?

Please no negativity, I get enough from my husband.

But, really how do you get over it? I know it’s not a very good thing to be but, I can’t help it. My husbands constantly throwing it in my face. I’ve tried working on myself and he just makes me feel even worse about it. Anyone else deal with this? I was never insecure before my babies. I love them beyond everything and well my body is another thing. I gained 70 pounds since being with him. I don’t feel enough for him anymore, I don’t feel attractive. I feel like I’m losing my mind over this. 😔
