There is always hope. I am so sorry this diagnosis has become a part of your family’s life. It is a challenge but it can be brought under control. I know you are new to this and it is very overwhelming. Don’t hesitate to get support for yourself if possible either by talking to a trusted friend, or family member or even a counselor of your own if that is a possibility.
As for your husband’s inability to believe there is anything wrong, that is a real condition called Anosognosia and is very common amongst schizophrenics.
You may eventually have to set some strong boundaries with your children being involved and make it clear that he will have to stay in treatment and take his prescribed medications if he is going to stay with you and the kids for safety reasons.
He would likely never want to knowingly cause any harm to you and your family but psychosis can be very unpredictable at times and there is always a chance he could act on a false belief. Always safety first.
If he is unemployed for more than 1 year due to complications from his illness, he can apply for SS Disability which comes with health coverage and would help with some family finances. There are many steps you can take to start the path to recovery for your husband and ultimately your family. There is no easy or fast fix. It takes dogged determination and hard work. It is a combination of having a good doctor, good communication with that doctor about what symptoms are presenting every day, good medication compliance, a low stress environment and a generally healthy lifestyle otherwise, healthy meals, no alcohol, and lots of sleep. Recovery is slow but once you begin to see it hope will return again. Patience is critical.
Welcome to this forum and please ask any questions that come to your mind, somebody here will have a suggestion. Read some of the stories and maybe some ideas or questions will come to mind.
There are a lot of parents and spouses and siblings here going through the same thing, often everyone is in different stages of progress. I am in a good place with my sz son right now but I went through many trying years to get here. I am glad that I stuck it out, there were times I couldn’t believe that my son or I would make it. We did though, and I never take that for granted.
I think things will definitely get better if you can get your husband to understand that whether he thinks there is a problem or not he will have to listen to the doctors if only because his recent behavior has shown he can sometimes get ‘out of control’ and that can’t be okay with your kids at home. Hopefully he will agree and stay with treatment even if he doesn’t really want to.
