Marci,
I'm 3.5 months post-op for a similar size tumor, and I can say your attitude is a good one! Positive outlook is quite crucial in recovery, and it's what they attribute my fairly quick recovery to. Being a runner is also a plus as you go in - just don't expect to be running again quickly (in both senses of the word) and allow yourself time to heal. My advice about what to bring: I didn't use anything I brought, and catching up on reading and "Thank You" cards was just a fantasy. I can say eating was a priority because I couldn't/unappealing. Organic applesauce was a lifesaver, prune juice, banannas, ect. Also if you have a favorite pillow...Contoured, down, latex, etc., bring it beacause the hospital's are funny textured and noisy if that makes sense.
Anyway, you'll do great! You have two teams, both on the same side against one (benign) tumor. The first is your Doctors, the second is you and your family. You guys are going to win, and I'll be praying all day Tuesday to that end!
All the Best,
Jules
