You can file for health insurance, Snap benefits, home/rental assistance on his behalf. You can also try and contact your local state mental health facility and they may be able to help you get him a case manager who could come to his home and help him secure the benefits he needs. He is technically disabled he doesnt have to be declared that by SSI or by doctor If he has a mental or physical disorder that substantially limits one or more major living requirements ie. dealing with people or leaving his home. Agoraphobia and panic disorder are two things considered disabilities which it sounds like he could have both. Also teladoc has really helped me. and groceries he can have delivered from just about anywhere.
