I was wondering what to do with a Father who is mentally ill but my mom has alzheimers and needs my help. I have been going over to my parents house for the past 6 months to help out my dad with mom who has alzheimers. My dad is just a hateful narcissitic crabby ill tempered old man. He has been like that his entire life. My bothers and sister have nothing to do with them anymore... all because of my dad. My mom is very sweet and I believe she has gotten better since I have been going over to their house to help... My father appreciates what I do... he tells me thanks sometimes when I leave... but I can't deal with his behavior towards me. I try to carry on a conversation with him... but with his mental issues... half the time he ends up yelling and cussing at me... for things like asking a question????? He has a horrible temper and needs help himself... my mom put up with his temper her whole life... she's an angel... I believe no one else would have... but anyway... he thinks he can treat me anyway he pleases... just because I am his daughter. He got mad at me last week because I literally just asked him a question he thought I should know the answer to... He was yelling and beligerant with me... just crazy stuff... so anyway I told him I was leaving and wouldn't come back. Now I don't know what to do......whether he's belittling me... telling me I don't know how to do anything right... whatever the reason... I can't deal with him anymore... I am feeling depressed and down a lot... just like I did growing up and having him as a father. ..it's like I am back in that time in my life again... that age again... and I hate it... I left home at 18 to get away from him... but I want to help my mother... I miss helping her... but I will not let my father destroy my happiness either. Any help or suggestions would be appreciated... thanks.
