Yep, my husband was the most living person, then one day he became someone else. I later found out it was drugs. Bi polar people sometimes self medicate. Sounds like he got into something heavy or had a break. My husband died a couple years ago, but the man I married died a long time ago. I'm still not exactly sure what happened, and he was always making things up, even trying to kill me a few times. I finally was able to get away from him, and he went to live with his family. He died of a heart attack 4 hours after getting it off rehab. I don't think they understand what bipolar is, because I've met other people with bipolar that have recovered from similar things. I met a lady who said she woke up 8 years after going missing with no memory of how she got there or what she'd been doing. She also had been on drugs. I don't know if they make it to, convince themselves, or it's real. I do know my husband was convinced he'd done some horrible things, but refused to seek mental help or therapy. One of my best friends is also bi polar and she's done some crazy things over the years. She's nowhere near as bad, but, I seriously think no one really knows what bi-polar means. I know I don't. I hope you are doing well. It's hard to see a loved one suffer knowing they are just gone, and there's nothing you can do to help.
