Emotionally Abused

So, my name's Angel. I had a best friend. We knew each other since we were 6. We were two peas in a pod. Things went downhill when we hit middle school. We started going different directions in life, but I guess she didn't like it. She became incredibly manipulative, making me demean myself and sacrifice my self-esteem for her, making me keep secrets from my family and trying to control the people I let into my life. She also made me feel worthless for having my own beliefs. She would debate at me about my religion, basically ranting about how it was wrong and out me for my beliefs to other people. I could never give enough or be a good enough friend for her. Something else was the cause of all her problems and if I dared to disagree with her it was a constant stream of how I was a terrible and worthless friend. This was my life for five years. It's been almost a year since I ended our friendship.It did not end quietly or stress free. Since then I've been having anxiety issues and problems with letting go of the bottled up emotions I have as well as struggling to open up to my family. Has anyone else had a friendship go so terribly wrong?
