For what it's worth: It's never too late to be whoever you want to be. I hope you live a life you're proud of, and if you find that you're not, I hope you have the strength to start over. -F. Scott Fitzgerald More
Walk away. I walked away from a destructive friendship and it was one of the best things I ever did. I still miss her and I still miss what we had been before we both changed, but I will never regret the moment I finally stood up for myself & walked away.
