I am glad everything is going well for you.
It is normal to feel nervous before treatment, who wouldn't, no matter if it is microsurgery or radiosurgery. Keep focusing on the potential for a positive outcome; all treatment methos nowadays have very high rates of success.
For what it's worth, I was a nervous wreck before treatment, because of all the conflicting last minute opinions ( must have lost 5 pounds the week before because of the stress). The procedure itself was tiring of course, but afterwards I felt fine, and after a nap I had a nice supper at the hotel we were staying and was able to go for a walk. Overall, I would say that it has been a breeze since then, and I didn't have any issues. I have my 6 month follow-up appointment coming up on the 28th, so I am waiting to see what the doctors will have to say.
We will keep cheering for you, and I am sure everything will go well.
