Having a special needs family member is difficult in every situation--especially on siblings that may end up responsible in the long run.
My cousin had Downs Syndrome, and he was institutionalized his entire life. Our state once had excellent care in group homes, but got out of the mental health field 30-40 years ago. Then Blake went to a nursing home for a few years.
The state ended up finally placing him with Volunteers of America where he and two other gentlemen lived in a rented triplex. He'd go to a day care center during the day and come home @ 4:00 p.m. where a gentleman took care of him until being relieved @ midnight. Another gentleman took care of the guys until they left the next a.m. I cannot tell you how wonderful Volunteers of America was until the end.
My cousin was very happy, and he received specialized care my elderly aunt (who died 3 mos. short of 100) couldn't provide. After all, Blake had his own life to live. He was happy to see his relatives, but 20 minutes later he was glad everyone left.
Too bad you're not mobile. I understand Atlanta has an incredible autism clinic and it's a very low cost of living city--for such a major city.
I actually think that institutions like Walbrook (Rainman) are far safer than individual group homes where abuse - I'm told - runs rampant with fewer eyes watching over disabled individuals. My hope is to outlive him, but I doubt that'd happen since my health is poor and he's still so young.
If our daughter chooses to be a teacher, I'm assuming she'd have more options on where to settle down, than if she decides to work in IT (despite likely making several times more money in IT than she could as a teacher). We probably shouldn't tie ourselves to her -- it's so unfair to her to have to take on this burden -- but I don't see any way out, esp as we get older and need help with him. Thank you for the heads-up on Atlanta. Someone else also mentioned MN. I am taking good notes on all these suggestions and hope I get more as we decide where to ultimately settle down.
