ET, first, welcome to HW, glad you found us, if late.
Yes, the Gleason 8 isn't what we/you would want, yes the negative margins are a positive, as is the zero psa so far. Really, the facts are that you can do little beyond your current course. Your doctors have a good plan in place, so I am sorry to say, you're gonna just have to accept that everything that can be done is being done, it appears. You're gonna have to sweat out those 3 months PSA tests. Maybe with each one, you will toughen up some, but the reality is you're gonna have to do them, there's no guarantees of the results, but the process will play out, worrying about
it or not. I suggest that you decide that you will take each day and make it THE day, and live like you're gonna be here for another 50 years. You can (and will) worry, but you need to try to minimize it, in relation to the rest of your life. Be/stay active, exercise regularly, choose to do other things, remember the good things in your life, and let the worry go, as much as possible. In the meantime, hang here with us and we'll be glad to share with you...
