Surgery After Weight Loss

I'm a little nervous. Yes, I'm only 21, but I'm also over 300 lbs. I've lost quite a bit of weight, and while I may be jumping the gun a little (planning this kind of stuff keeps me motivated), that is a LOT of weight to lose. I've always been more than a little overweight, and I don't think my body is going to shrink well.

I'm not sure exactly what I'm looking for here. Advice? Insight? Has anyone ever gone through this? Tummy tucks? Even boob jobs? (I know I won't have any boobs when I'm done with all this.) I'd love to hear your stories.

And also, what about financing? I'm hoping this goes by quickly (it won't, but I can hope), but at the same time I need time to fix my credit. Like a lot of people right now, I'm unemployed. I don't have the money to buy gas for my car, let alone pay my credit card bills. And in 5 months I'm going to lose my insurance. I don't know what to do. Any advice on this front? Is there a program that might help me get financing? Or do plastic surgeons have financing options for people with bad credit that I don't know about? I'm not just thinking aesthetically. I know someone who lost this kind of weight and got medical issues because of it, but her insurance covered it because it was a medical necessity. I'm just afraid that I'm going to have problems and not be able to do anything because I have bad credit and no insurance.
