For the past couple of weeks, I've been having moments of feeling "loopy" or drunk or drugged. I had an MRI this week and found the cancer is now in my brain. On Tuesday, I will have Gamma Knife Stereotactic Radial Surgery.

Wear purple for me on Tuesday. If you know me, no explanation is necessary.
