Good luck tomorrow. I too have a permanent bag, coming up on 16 years now. Best decision I ever made. There is a learning curve in the beginning, butt after a while, dealing with it is like brushing your teeth. Second nature.
There is a web site UOAA. United Ostomy Association of America
https://www.uoaa.org/forum/index.phpthat you might want to check out.
Just remember to walk, walk, walk, the hospital halls. I truly believe it does help in the healing process.
You can do this,
