Hi @ladyliz46, welcome. It sounds like you have a boatload of concerns for your son. This can't be easy for either you or him.

You might be able to find some assistance using the Social Care website called FindHelp. Type your Zip code into this search engine https://www.findhelp.org/
Find Help can help you find financial assistance, food pantries, medical care, and other free or reduced-cost help in your local area.

It can be a challenge to help someone if they don't want help or don't think they need medical attention. Does he have a doctor that he trusts?
