Your fears and concerns are all very valid. I know I can come off as overly positive. I had surgery in July and am just so damn happy to be alive. But I was absolutely terrified before surgery. Of being diabetic, of losing weight and muscle, of never being able to eat foods I wanted again. I remember bursting into tears when they called me from the waiting room. Just so scared. But when you find a surgeon you trust and weigh the pros and cons and endure the surgery, and then find yourself being told you are cancer free...there's just no feeling like it.
