My father is dying of liver disease and hasn't told my mother i'm experiencing psychosis where do i start?

Family Discussion: Ask the family md +\-oncologist to have a family meeting to inform mother. This should be done with sensitivity to her emotions, as she's overwhelmed already. Informing shows respect to her. She must also know that you have treatment and support, are compliant with medications and are stable, so she won't worry about another medical crisis to handle.
