Hi Presence. I imagine this must be the most stressful and upsetting thing you’ve ever had to deal with, especially since it involves innocent people and it’s such a disturbing topic. Believe me. I know how you feel. You’ll get through this. Here are some thoughts based on my experience.
First, there’s a good chance your son will not “shake” this aweful theme of delusional thinking, no matter how many people contradict his accusations. He might even come up with paranoid reasons as to why those people are not admitting his truth (ex. They’re part of “the conspiracy”). During some periods, it may seem like the delusions are going or gone, but they’ll probably re-emerge during a stressful moment.
Second, you may need to mentally prepare yourself for the possibility that this theme of paranoid delusional thinking could also eventually involve you too. I hope this doesn’t happen, but it could. I know this sounds horribly sad, but I would strongly suggest you make sure everyone, including you, knows not to attempt to have any physical contact with your son (ex. Hugging) without his explicit permission.
Third, if your son meets with any doctors, nurses, counselors, etc., I would not only recommend you warn them ahead of time about his fears/paranoia surrounding his own personal safety, but I would make sure there is always someone else in the room at all times. Your son may currently be talking about past experiences, but there’s a good chance he’s paranoid that something new is about to happen to him.
At this point, all you can really do is try to be pro-active, to prevent more damage from happening and hopefully not fuel the fire of this delusional theme. You’ll get through this. For us, it’s happening through medication. Some day, it’ll be a horrible distant memory. I’m looking forward to that for us and you.
