There's A Body Under All That Skin...Right?

I'm sure that tons of people have asked this question before, but here I am to ask for myself! I've lost 65 lbs, and I have a lot of loose skin on my stomach. I know that it's actually lose skin based on how thin and wrinkly it is. If I lay on my back, and lightly touch my fingers to my belly, I actually leave little dents. It's disconcerting to say the least, and it's really killing my confidence and motivation to keep going. I'm 26, so from what I've read, there's a possibility that it might tighten up, in a couple of years, maybe, if I'm lucky. Any advice from people who have lost large and dealt with this?
