I don't think it matters what I think, just be careful this weekend when you are snooping and don't do anything you will regret later. I agree something is wrong with her physically, and I agree an appointment with Mom is very odd in deed. Let us know what you find and although I don't think it is the best idea, you have to do what you have to do.
Good luck and enjoy the weekend!
