Growing up and growing apart...

I am a loss for what to do. I don't want to look down upon any one's way of life and I don't want to lose friendships over differing beliefs. I just want to live in the healthiest environment for myself. Honestly, at this point none of you benefit my health, sanity, well being, or spirit.
So should I stay or should I go?
I don't want to be the middle person- I've been that person more times than I can count.
I want to do what is best for me, and that might mean losing all of you.
I am tired of loving and hating at the same time.
So, goodbye.
