Why am I here?

What is that I am supposed to be doing here on this earth? I have nothing to complain about and yet I find nothing to live for. There are many people much worse off than me. Yet I have no hope for my own life. I have no one to call on. I so long to leave this world. Why can't I find my purpose? Why am I here? Work has no meaning. Eating, sleeping, breathing, I don't know why I continue to do anything. I have no value to the world I live in. I've prayed and prayed for the answers and I even felt that I met God face to face. All that has done is to keep me here one or two more days. I have no desire to go on. You might read this and say, "You are suffering from depression." NO, REALLY?!? But every time I tried to get help, the door gets slammed in my face. So I've stopped asking. This is not a battle I can win on my own, but that's what everyone has told me in not so many words. It'll be sheer luck if I make it to my 29th birthday. I'm surprised I've made it as long as I have. I just wish someone, anyone would see through the act and help me. I've hid for so long. I don't know who I am anymore.
