I've been so insecure and It's my husbands fault.

My husband is always talking Shit to me acting like it's unintentional, a have the slightest overbite. I was laughing really hard a few months ago and he laughed with me then he said a comment like "lol your donkey teeth" I ignored it. Ever since then I got really self conscious about my smile that I started just covering my half my top teeth when I smile with my bottom lip. I told him I wanted to go get a haircut a few months ago and he replied "you should just shave it since it's all fried" he will always make fun of "my big head" I never paid attention to how big my head actually is until he started calling me on it now that's all I see. He makes fun of my "round nose" "my round head" "my tiny lashes" he keeps poking at my double chin and laughs. Today I was telling him that I started replacing my lunch with a green juice and he was like why aren't you eating !? That's why you got hella fat ! 😞 I ignored it and he acts like he doesn't say anything keeps acting like normal, he would always make fun of my toes not being done... there being a big very light brown spot under both my eye sides. So I've been going crazy so insecure, i keep having dreams that he cheats on me because I no longer look like I did 2 years ago. I've been trying to get my shit together... I've been trying to loose those 20 pounds I gained. I've lost 7 so far the past 2 weeks, I've bought stuff to make my lashes grow, tattooing my eyebrows so that they always look full, I've been massaging my face to help with the face fat, applying ice, face masks, I ordered this chemical peel to maybe help with my dark spots, I've started taking care of my face, my hair and shaving my legs everyday lol using whitening toothpaste ! I ordered invisalign from smiledirect because I can't affor 6k at the orthodontist...Fuck !! I've never been insecure and I've got to the point where I hate everything about myself.
