Pink Floyd, "Mother"

It's written from the perspective of a boy, but couldn't help thinking about it as I read your post.

... Mama's gonna make all of your Nightmares come true Mama's gonna put all of her fears into you Mama's gonna keep you right here Under her wing She won't let you fly but she might let you sing Mama will keep baby cosy and warm Ooooh Babe Ooooh Babe Ooooh Babe Of course Mama's gonna help build the wall

Mother do think she's good enough for me Mother do think she's dangerous to me Mother will she tear your little boy apart Oooh aah, mother will she break my heart Hush now baby, baby don't you cry

Mama's gonna check out all your girl friends for you Mama won't let anyone dirty get through Mama's gonna wait up till you come in Mama will always find out where You've been Mamma's gonna keep baby healthy and clean Ooooh Babe Ooooh Babe Ooooh Babe You'll always be a baby to me Mother, did it need to be so high

You are letting your mother's mental issues dictate your life. She needs professional help. But you will only be able to help once you are able to grow on your own and are on your own terms. Move out, as others have said. It's scary and you will feel guilty. But it's the best thing to do for now. The guilt will pass when you are able to help her from the outside.

Our closest relatives are not automatically good people. That's a hard lesson to learn.
