onlyitj I have helped a friend when they lost touch with reality and they ended up in hospital which was safest place for them.
The hospital is a place that they can try meds and keep close tabs on patients. They also have other treatment options.
I am relieved you are seeing doctor. Admitting gives them time to work with your wife to get them stable and it may just be the vacation you need to get back to some kind of normal and take care of your self care needs and the needs of your children. Hoping for the best outcome.
