Seeking expert counseling is a sign of strength. A personal relationship with a caring professional is proven clinically effective.
I believe that I can help.
I am so sorry that your son, and your entire family, is going through this ordeal.
It seems as if your son has a psychotic disorder. There is a remote possibility that this disorder is induced by a pre-existing medical condition or by some use of medication, but most likely it is a psychiatric disorder, most likely Delusional Disorder, Persecutory Type, unless he is also having other symptoms such as hallucinations and negative behavior, which would then be Schizophrenia.
Either way, if he does not get diagnosis and treatment is symptoms will continue to manifest and he may continue to deteriorate.
Because he has paranoid delusions he will not even trust you, his mother, and will not voluntarily go for treatment.
If he makes suicidal or homicidal threats then he can be taken into custody for brief observation.
In order to get him in to treatment he will have to be judged to be unable to make decisions for himself.
Since the laws vary from jurisdiction to jurisdiction, your best option is to speak with your local country or district attorney and find out how to proceed.
He will be better off if he can start therapy right away, but he is not likely to volunteer and will have to be coerced.
And that means coerced under the law, which may be difficult to do.
You can have him involuntarily committed if you come up with evidence as to why he needs help. You may need the help of a private attorney as well. That is what I would do for my loved one. It is always difficult for families when one member has a serious paranoid disorder because they will not trust you to help them, and they will think that their delusions are real and those who don't agree are lying to them and are the enemy.
I urge you to let legal advice and get him into treatment.
I wish you great success and shall keep him, and all your family, in my prayers.

In regards XXXXX XXXXX family meeting we are having this week, how do we express our concern about the change in his relationship to us? I feel that he does have some trust in me, as he continues to say he loves me and that he believes me when I explain that I don't have a clue about any of the bizarre things that he thinks are going on. Do we indicate to him that his suspicions are irrational? Do we act as though nothing is happening? How do we give him a sense of being loved and cared for and supported in all the ways we possibly can?
