I’m sorry your wife is still so symptomatic. I think it’s really good she is going somewhere to be treated.
Since this is what’s happening, I hope you take the time for yourself to rest, get some fun activities in each week or so, and let yourself process what is happening and what has happened.
I don’t know what will happen with your wife, but 75% of people who experience psychosis recover to some extent. So there is hope.
You don’t have to decide anything right now. Get yourself in a healthy, well-rested place and give yourself the time and space you need.
