How do I tell my mother I do not want to go through recruitment?

[CaliforniainTx]

This is honestly one of the hardest things I have ever had to do. It might seem like a petty teenage girl problem, but I love my mother so much and I know how much this means to her.
She and my grandmother are Alumnae of Delta Delta Delta at the University of Alabama in Tuscaloosa and my sister is an active member of Delta Delta Delta.

Over the past 4 years of high school, I have thought heavily about this. I know it's bad and I should have told her earlier but I honestly thought this feeling would go away.
Ever since I was a little girl she has told me she can't wait to be sisters and I know how proud of my sister she is for pledging DDD. We don't live in Alabama, but she is still best friends with about 7 of her sisters and every now and then they do go out to brunch together. About 2 weeks ago we met up with them and 2 of the ladies have daughters who are graduating this year like me. My mother and her friends kept going on and on about how they can't wait for us to go through recruitment together and it will be wonderful for us to all be sisters together. They kept going on and on about how now is more important than ever to being prepping and to focus more on my conversational skills etc. My mom is so ecstatic at the fact that she thinks I will be going through recruitment. I know how much this means to her but I honestly do not feel being in a sorority is for me and I think it is only something that should be done when you want it.

My mom always tells me it was one of the best decisions of her life because even to this day, she's still best friends with some of her sisters and she goes on and on about how much fun I would have and how naturally well rounded it makes you.

I know I might seem over the top about this, but I honestly cannot bare to break her heart.

How do I tell her? I feel so bad about this and I haven't even told my father how I feel because he is a SAE and he always talks about how beneficial greek life is and that it goes just beyond memories.

btw, I was accepted into Bama, Ole Miss and TCU. Naturally, growing up around Crimson Tide spirit I DO want to go to Bama, I just don't want to go through recruitment.

Help?
