Yes, it is severe. He seems to have shifts of consciousness and personality. I obviously can’t diagnose him but I think he has DID. He has “woken up” in the middle of doing something and didn’t remember what he was doing or how he got there, etc. Once in a while he asks me what we were talking about in the middle of a conversation, and then has a totally different take on the subject than a moment earlier. There are at least two “versions” of him with different attitudes about many things, and occasionally (when he brings up a topic we have already talked about) I have to remind him what “the other version of you” said about something. It’s a little uncanny, tbh.
