my family has a history of psychosis and we r now dealing with the 3rd sister who is displaying psychotic behaviour. because of her personality which is a very sweet loving woman it is hard for some members of my family to recognize that she could possibly be mentally ill. she has been displaying paranoid and accussatory delusions of everyone around her for the last 4 years . my parents and her twin sister seem to be the ones that r the most in denial and don't discourage this nasty vindictive behaviour. her marriage has broken up and now my surrounding and extended family are all fighting and don't want to be around each other and we use be very very close to one another. I have spent the last 4 years trying to tell my parents that my sister is mentally ill but because she looks so normal on the outside they refuse to listen to what i have to say. my words fall upon deaf ears. this has driven a wedge between my family to the point that we don't spend holidays and special occassions together anymore because no-one wants to be her next victim of abuse or accusations . she is not a nice person to be around anymore.. . some of my sisters delusions are people stealing from her, people manipulating her bank account , her husband cheating, people stealing her mail, she sees all people and every situation in a negative way which is the opposite of her when she is well. what i need is some literature on psychosis signs and symptoms and effects on people families and how families can cope and deal and recognize these behaviours so that i can show my parents that what i have been saying is really happening to us and that something can be done. could u direct me to a web site on these issues or give me some advice on a different approach with my parents. i thank you very much for your time and appreciate any advice or help u can give me thx again
