Freaking out about dental surgery and upcoming surgery

I'm totally freaking out about tomorrow. Tomorrow I am getting all of my top teeth removed (due to medication changes and dry mouth and general teeth grinding) and I will have top dentures for the rest of my life my face will be different. I never thought that at 43 I would be needing this and next year I will most likely need my bottom teeth removed as well. I'm already in so much pain from other things wrong in my body and now I will have a mouth full of pain for the next few weeks. but on top of that next week I am going in for surgery as well.
