My wife does not have sz, but she is schizo-affective bi-polar and I notice that there seems to be a lot of similarities in those conditions, which is why I lurk on these forums to see what other people are doing to handle a similar circumstance.
For me, the shoe is in decent right now. I’m watching as my wife, once again, has stopped taking medication, started laughing maniacally at all hours of the day, screams and belittles the children, curses and profanes against family members (mine and hers). And once the shoe hits? It’s not going to be due to her having a revelation that she is sick and needs help. It will probably be an alcohol soaked bender leading to arrest or an involuntary commitment.
I’ve had that feeling for the last 3 years, and the only relief I get from it is when she is initially put into a hospital involuntarily. The relief usually fades within a day or 2 when I realize that the hospital wants to release her ASAP.
