Gained so much weight!!

While pregnant I gained 68 pounds I have no idea how! I did horrible I was 120 pre-pregnancy. I’m 10 months pp and 157 right now but I’ve been this since 4 months pp and seems like I can’t lose any more weight not even a damn pound!! I’ve tried so hard going for walks, diet, I have even done intermittent fasting since I heard so many great things on that! I’ve never been this heavy and feel so horrible, so unattractive, full of stretch marks, with so much weight, I used to feel cute and sexy with lingerie and now everything looks ugly on me. Anyone else struggling with weight loss after having a child? Ladies be honest with me if y’all experience this before have you gone back to your normal weight or no? Sorry just wanted to vent.. my husband doesn’t seem to understand my feeling, he says I’m still sexy and beautiful but I know it’s not true!
