Thanks everyone.
It wasn't until I saw a number of peoples' pictures, here and other places that it dawned on me what was going to happen. Scared the crap out of me, but like one man said "i'll cross that bridge when I get to it." The thought of surgery scares me, but I decided I would do whatever it took for me to feel better about me. If that includes starting a bank account specifically for medical expenses then so be it.
I can't let it stop me.

Right now, this minute, you've already got all the skin you're ever going to have. It's just stuffed full of fat now. You won't grow any more skin as you lose weight, fortunately.

I am not going to overly worry about it but I do hope I don't end up with big bags of skin hanging all over!
