So, I feel funny writing about this, but...has anyone else ever experienced a negative change in their social life post-op?

I had my surgery back in January. Although my physical health has made drastic improvements, I'm afraid my mental health has taken a toll.

I noticed people have been treating me very differently since having the surgery. I've been getting so many rude comments, I can't keep up. They think I "took the easy way out (not realizing it was actually quite the opposite: the last resort)," and/or are freaked out by all my new eating habits and restrictions or are saying cruel things like "oh, you'll just gain it back like so-and-so did anyway, you watch." A lot of them have also proceeded to claim my changed appearance "weirds them out." Some of my now ex-friends have even gone so far to complain that I "betrayed the body positivity movement by giving into society's expectations of what women should look like." What the actual heck? Even dating, something I thought would get better as I lost weight, is just as bad as it was before. Since I can't drink alcohol anymore or eat a lot of foods, guys have been pretty hostile. Although I've been private about my surgery while dating (simply stating I have a strict diet I need to follow), that hasn't stopped guys from being mean or rude.

Bottom line here is I've lost a lot of friends this past year and my love life is no better than it was. I'm extremely lonely and depressed.

Has anyone else ever encountered this? What can I do to change it? Why is there so much social stigma towards this surgery?

Thank you all for the thoughtful and helpful responses! I sincerely appreciate it very much. As always, every answer means the world to me. Thank you.
