Jeanne,
I empathize! I reviewed all these forms only a few hours before my procedure, and I was rather amazed myself. In person, the doc and I talked primarily about hearing and then the forms come and it's a bit overwhelming.
I've also done some reading post-treatment and it can continue to be daunting.
But since I know you've been here and doing your reading, thinking, discerning, and discussing---I hope you have become comfortable with your decision. I came to the conclusion that there's more risk to my health each time I go out on the highway, buy the foods found in grocery stores, and walking the dog. Risk, unfortunately, is everywhere and we can't stay in our bedrooms in paralysis.
The good folks here helped me through the hard moments (which still occur!), and I affirm how you are feeling. Hang in there....although I'm a believer that sometimes it's okay to "let go" and feel what you are feeling.
Take care and enjoy your weekend. Treat yourself!
P.
