@mlhaeger You are in a very tough and sad situation! You are responsible for total care as far as meals, laundry, trips to and from doctors, everything except personal care? Have you contacted the Area Agency on Aging in your town? I know your son isn’t “ageing” but they may know of an agency that could assist you with your son. And they may be able to help you find someone to talk to, like a therapist.
Do you have anyone who helps you and your son now? Do you have any family?
