Awwwww Debz..I feel for you as you know I have been struggling myself so I can totally relate. Hugssssssssss
As for your fiance, I have the same issue with my husband. He now tells me I am toooo thin and he likes "thick" woman. But loves me no matter what size I am! I know how frustrating it can be. I just don't talk to my husband about what I look like because I know his answers are never going to please me inless he lies..
I have no answers for you on your meds, before surgery I was on a zillion different meds but after surgery my surgeon told me to stop and see how I felt and I thought I was doing really well off of them but now after 2 years out I am thinking I probably need them or something at the very least.
Hang in there sweety! Sending you hugsssssssssss
