Symptoms of psychosis can severely affect a person’s ability to function in many areas. You may be concerned about leaving your relative alone because you are worried they may forget to take medications, use harmful substances or harm themselves. It can feel overwhelming to constantly watch for symptoms in your relative while also dealing with the impact of the illness on yourself. Worrying about a relative can also negatively affect your emotional and physical well-being. You may be at risk for stress, poor sleep, weight loss or gain, depression and anxiety.
