@Molly, it is very hard dealing with the aggressive speech and accusations. I try to approach him every day with a smile. I avoid confronting his delusions, just show sympathy for the distress he feels. Mostly I succeed, but sometimes my patience just runs out.
This morning I made the decision as his guardian to have him admitted to the psych hospital. He had managed to hurt his back while swinging a chair at something, so… at least even he can see he was potentially a danger to himself. And he was breaking stuff - not just his own property, but also a door in the house. And he was making threats to hurt others. Mostly general talk, not naming anyone specifically, but - at this point, I just felt he was going to continue to escalate.
I will drop off some clothes for him later. Tomorrow, my husband is scheduled for surgery, so I won’t see my son tomorrow, but he is angry enough, it probably is just as well. I have learned to use a hospitalization to regroup.
