Soon to have dentures

I'm slated to get 6 top teeth and 1 bottom tooth extracted in a few weeks.

I'm 53 and very nervous.

Worried about pain and recovery, worried about dentures not fitting right, worried about how I'll look...

Is there a "So, you're going to get upper dentures" book or website that will help me prepare for my EDay as well as the first few days (weeks?) afterwards?

Side Note: I have an overbite with my upper teeth. Will this be a issue for me when I get the upper dentures?
