Proud but Worried

So, I'm very proud of myself for losing 40 lbs, so far. I know I am healthier and happier with each pound I lose. But, I'm starting to worry. I look in the mirror and I see the excess skin just hanging there. I can see my muscles but those do not fill out the loose skin. I still have at least 80 pounds to go. I don't know what I'm going to do with all the excess skin. I've looked into a body lift and that's over $5,000. I don't have that kind of money. On one hand I'm loving getting thinner and healthier but what problems am I going to face with all that skin? I'm really worried.
