Bad case of Diverticulitis

I've been off work for 3 weeks now with some sort of gut issue. Yesterday was the third trip to my doctor since it started, and he finally prescribed some antibiotics. I've taken 2 tablets so far, and I am already feeling a little better.
My house is literally 5 minutes from the hospital, and I was seriously thinking about going there on the fourth day of this illness, but didn't think that I could get there without shitting myself.
I have had blood and stool tests done but nothing conclusive. Finally told the Dr yesterday that if this is how I'm going to die, then make it quick, cause I don't want to live like that. I've lost over 20 pounds already, and I have no appetite most days.

Worse yet, my wife has had this on and off for 6 months now, ridiculous. She's been to the Dr several times.
That sounds environmental if you both are getting it
