I'm totally comfortable with rotating it through everyone here who wants to do it -- there are few enough that each could take a shift. I also know there are "co-hosts" but I wonder if that's really needed in this small group. I'm cool with any of the above! It'd make total sense to rotate the hosting around this group.
Diabetes would definitely be a hard process to get used to. As I explained earlier, a close friend has type 1 diabetes and watching her go through the constant glucose ups and downs is awe-inspiring. She's considered a "fragile" diabetic, and medically I can see why. But damn, you'd never know it from the way she attacks life! She lets little stop her. She cleans for me once a week, since I can no longer do most of it myself. I've literally told her I'd fire her a couple of times when she clearly was in bad shape and wouldn't stop to do what she needs to do to take care of herself! When she's stubborn like that, I just ask if I have to fire her again to get her to stop!
I've learned to keep a supply of OJ and candy for her -- I can tell when her glucose is crashing, sometimes before she does.
And she's been dealing with it since she was 12, so give yourself a break -- you're dealing with the pain of colitis & so many GI/systemic issues -- there are going to be ups and downs. And sometimes our bodies do have minds of their own -- I watch her and, even when she's done everything right, her body goes kaflooey. Mine does too. I think it's a matter of getting comfortable with unpredictability, not always an easy process!
