Lack of Libido?

I was sleeved 07/04/2017 and I'm down 30lbs as of today (whoop whoop)!

A little background, I have a son that just turned two. Before I got pregnant my sex drive was through the roof. I had lost 150 pounds with weight watchers and had been maintaining for about 2 years at that point. Despite working out while pregnant and being mindful of what I ate, I managed to gain about 80lbs with my pregnancy. When I was about 6 months or so, my libido just DROPPED. I had zero desire to be intimate or even kiss my husband. Fast forward two years later.....and I still am struggling. I've went to the doctors multiple times and they tested my hormone levels, thyroid, you name it and everything came back fine. Not that I was hoping for bad results, but them telling me I was good to go didn't make me feel any better about the situation. I'm not sure if it is more of a mental thing that I'm struggling with and is causing me to feel this way. I met my husband when I was thin and despite him being very affectionate and understanding of what I'm going through, I just feel unattractive and would honestly rather run a marathon in Death Valley wearing a snow suit than have sex.

Has anyone else ever went through this?
