Thank you so much for reaching out, you are facing a very challenging time and we know that the more you reach out for support, the easier it will be to deal with the situation. We would recommend to neither agree nor disagree with the delusion. We have a module in our Strengthening Families Together program focused on how to communicate with a loved one living with psychosis. This program is free to anyone and you can contact a local Regional Educator to find out when the next Strengthening Families Together program will be running in your area.
We also have a Family Toolkit available online with a chapter on "Communication and Problem Solving Skills" (http://www.bcss.org/documents/HTH/famil ... LowRes.pdf
