@Former-Member Have you ever read a book by Anne Deveson called "Tell Me I'm Here"? It chronicles the challenges faced by Anne and her family when her son Jonathon is diagnosed with schizophrenia. Her son was extremely ill at times and totally denied there was anything wrong with him or his often bizarre actions and appearances. There is also another book called "Recovered Not Cured" by Richard McLean and chronicles Richard's journey with schizophrenia and also his journey of recovery. Perhaps your local library has copies?
Both these books (firstly Richard's book) made me realise that there was indeed something wrong and Anne's book I read during my recovery from my first episode, made me realise what my family went through because of this illness. Both books gave me much needed insight.
Unfortunately your son's lack of insight into his illness makes seeking help for him difficult. You so desperately want to help him and support him, but his behaviours must seem extremely taxing and heartbreaking. I think the best thing you could do is offer him to come home with you but under the proviso that he agrees to be assessed and treated for his illness. You simply cannot keep supporting him financially and have him reliant upon you when he is out of money, if he won't at least give something of himself back in return.
I'm guessing you want your son back. I do hope you get hold of Anne's book especially, as she has faced similar circumstances and offered some great advice.
