Help me be happy again

I self harm. I cut. My life is a mess. I'm never perfect enough. I'm never good enough. NEVER. And no one loves me. I had a best friend once. We were so close. I told her all of my secrets. She up and left me. And it's sad ya know? Walking by someone that you were so close with, and they don't even look at you! Ya, welcome to my messed up life.
