Mike, I've very sorry to hear that you were carted away to the hospital, but I'm glad that they discovered what the problem is. Are you now on medication for migraines? A friend of mine has to take shots for them.
It sounds like your life has settled down some and you've taken back control of it. I'm very pleased to see that work is going well and the students and faculty have been there for you.
Your children are keeping you busy...aren't they? I'm glad to see that you have a lot on your plate to keep your focus elsewhere.
As for your wife....she is a fool....she's lost the best thing that she ever had...you, as her husband. What a fool.
Please take care of yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
