Oops. Sorry I missed it when you did say you were an only child. Only children ARE more prone to being zeroed in on, as Missbelle says.

I won't get into my personal history here, but one therapist told me if I would have been an only child, then I would have turned out psychotic instead of severely neurotic.......But my mother had severe mental disorders herself.

Try to talk to your mom as maturely as you can. It IS worth a try. I couldn't talk to my mom.
