I Am Depressed Because I'm Lonely

Five years. Sad and depressed and lonely. These last five years were the most horrifying five years of my life. Much more than any horror films. Have you ever felt like you are watching a film but this time is on going for five years and u aren't playing the character but someone else is playing the role of your body? Well that's been my years. I have been so lonely..that how many people I have tried..nobody stayed to understand me and talk to me and help me. They just leave when they find out I am a bit weak. My friends, family and even my girlfriend,they left me when they got to know am weak. I know all the things I need to do..but I get weak moments and need someone. This loneliness kills me. Help
