Well, you've already done the hard work yourself by losing so much weight, so why feel bad about employing some surgical intervention to help with the difficult bit that is left over? I think the problem is when people have unrealistic expectations about 'plastic' surgery, thinking the effect will be greater than it actually turns out to be and believing that the surgery will transform their life for the better and be the end of all their problems. You certainly don't appear to be in that category. If you're embarrassed to tell your friends and family or worried about what they might think, then don't tell them! It's not the kind of surgery that would be obvious after all.
