Ten years ago my closest friend suffered extreme personal stress and over the course of a month came to believe I was conspiring against him (in a seemingly unimportant professional matter). It was entirely untrue, could largely be disproven by email records, and would not have been advantageous to me.
During a meeting at my house he seemed genuinely delusional, stormed out, and said maybe we could talk again in six months. Trying to help him caused a lot of problems for me. After 4 months he wrote saying he’d forgotten why we were fighting, but by then I felt seriously wronged and it seemed he was just magnanimously forgiving me. That seemed bad for his sanity and unjust for me, so I largely dropped him from my life.
Also I was very hesitant to renew our friendship when it seemed like I would be, on some level, talking down to him, instead of having a friendship of equals. But I missed the guy — the way he had been.
Most of our conversations were by email due to my friend’s hearing problems.
After four years I heard a lecture about how to talk to addicts to convince them to get counseling. It made the point that even if it seemed impossible for an inexperienced friend to break through to a person in denial, that often it could be done — because the person might already be substantially aware that they had a problem and be looking for a way out. I figured there was a good chance my friend realized he had had a “breakdown” and had treated me very badly — but was embarrassed to acknowledge it.
I decided to combine a feel-good “you’re important to me, and have done wonderful things for me” spin with an exacting e-mail analysis. I formatted it as a Powerpoint (since heavy conversation was a problem with his hearing, and I wanted the message to seem more important than an email). The email evidence pretty much refuted 80% of his claims against me.
What I got back was an absolutely perfect “Gish Gallop”. He had come up with five or six new accusations, each of which was more absurd than those of his earlier story. Example: “You told me I was over-reacting, which was very offensive to me.” The situation: when I said he was over-reacting I was almost literally stunned. In the course of 20 minutes he had revealed a non-existent plot, had made statements that seemed insane, and announced he was breaking off contact with me. (Insane type statement: “You made that pamphlet green after we agreed it should show Hope. Orange shows hope, not green!) It wasn’t said dismissively; I could barely say anything.
I am unfamiliar with modern mental health terminology, but right after the falling out I thought of him as having had a 'delusional episode". However I couldn’t get him to abandon his “paranoid” beliefs. As years went by I was struck by how much his beliefs were like a “conspiracy theorist”, such as a “9-11 Truther”, and seemed immune to what most people would consider logic and evidence.
During the Trump/Pandemic years there was much discussion on the boards about how to deal with friends and relatives who had bought into dangerous scams and preposterous conspiracy theories. There’s information on-line about the best ways of coping with those situations, but my friend doesn’t seem to be a classical conspiracy theorist. And while it would be foolish to take my one-sided story here as gospel, can anyone with substantial mental health knowledge make a best guess diagnosis?
(The “extreme personal stress” my friend was under: Potential blindness (on top of hearing issues), and an adult child seriously ill in the hospital with only one antibiotic left to try.)
