I had a really tough period (personally, not health) and sometimes you just don't see light at the end of the tunnel while you are still suffering. The good thing is, eventually, you will see the end of the tunnel and get out the other end. You will look back and have a laugh. It makes you stronger.
During my recent swordfight with the ramp spring steel, I though a lot about what you went through Pete. My injury was NOTHING compared to what you have gone through, and I used your strength and determination as they plunged the horse tranquilizer into my hand. My god that hurt.
Next year, around this time, think back at what you were going through. It is a great feeling knowing you conquered all your health issues.
