The quote I live by and why

"If you had a bad childhood the only thing that can happen is that it all gets better" These are the words that I live on. I've been through what I feel like is hell. I've about died five times before I was 16, my parents about got a divorce twice before I was 17, I went to a school and was bullied… one of them tried to kill me twice when I was only 14, all of these caused me problems. I’ve grown up with them. Most people don’t know… I was depressed and still have those moments. I have trust issues, anxiety. At one time I even had suicidal thoughts. I never did anything because I would walk in on my sister cutting herself and I remembered how much pain I felt just seeing it and I knew that I couldn't do that to my mom. I get yelled at everyday sometimes twice a day sometimes even more. I had a friend that caused me to get introuble with the law, story in itself. I have had 3 friends die of cancer when I was 12, 13, and 15. I don't know what to do, all I have to see is a small glimps of light. How is this small little glimmer supposed to keep my head up to be hopeful when everything around me is dark and falling apart? I see it now even the sun gets covered by darkness, but its still there shinning brighter than ever waiting for its chance.
