Chicory, I very much hope that you will follow up with the organizations that I identified. There are resources for help---AND HELP FOR YOU ALSO!!!!
I think you need the support of other parents who have adult children disabilities or similar problems. In the resource handbook that I mentioned---you will be able to find support groups.
You are not the first or only parent in OHIO who has had to face this kind of situation---you will draw strength and guidance and hope and courage from others.
I so hope that you will keep trying and not allow yourself to "give up". If you don't actively seek and ask--then all answers are "no" by default.
very sincerely,
dandylion
