I need advice!

I quit my job 6 months ago to be a stay at home mom! I hated my job and my son was having problems at school( he’s autistic). I gained 30 lbs, I feel so disgusting! About 3 months ago I couldn’t have an orgasm! I have been working out and on a strict diet! I told my husband that I hate my body! I’ve always struggled with my weight since my son was born! After I lost my baby chub, I was happy with myself! But, now I feel and look like crap! I look like I’m 4 months preggers! My husband says I look sexy and he still loves me! I’m trying not to stress so much about my weight but it’s so hard when you’ve been skinny your whole life and all of a sudden I look huge! I think that’s why I am having trouble have an orgasm! Last night me and my hubs were having sex and it felt nice but I couldn’t cum! So we tried with a vibrator and I came that way and my hubs got horny watching me! So I got on top on him and we had sex and then I came with him!
