I know I definitely was a bitch to my mom when I was 17 or 18...and looking back on it, I feel awful about it. But my mom always knew that this was a normal phase of development, and by the time I was 21 or so she was my best friend. It's awful that it has to be so hard (and I am dreading it with my own daughter!) but I have seen enough women go through it with their daughters, so I know it's definitely survivable.
I used to tell my female students this when they'd go off on how much they hated their moms...it's something everyone goes through, it's normal, and in five or six years you won't feel this way.
