You do realize you are closer to Chicago then southeast Illinois right? Going to south-east Illinois is kind of silly if you have a major city with a ton of therapists , doctors and support groups an hour and a half away. Why are you unwilling to travel to Chicago? It is a great city, I used to live there. Southbend is relatively close to Chicago. I know it sounds silly, but why turn your back on a major metro area with a ton of TG resources. I know the Chicago area very well, and you are being a little silly going to downstate Illinois, when the Chicago metro area is much much closer.
Southeastern Illinois is also pretty far from South Bend, IN. There is nothing down there but corn and soybeans.
Central Illinois is a little better, but you are still significantly closer to Northeastern Illinois and the Chicago metro area. It is the closest major city to you where you are living.
