When it rains, it pours

"I love riding. I actually feel my best when I'm riding, and not thinking about things." -- You wrote your own prescription for at least the depression portion of your trouble. Can't help you with the colitis issue, but at least you're willing to see a doctor (doctors) about it. Too many people, particularly men, avoid doctors and deprive themselves of the opportunity for relief. My advice is to throw yourself into the search for relief with the same passion you apply to hunting and motorcycling and you will get better.
