Is this a mental illness or just a feeling of nothing to look forward to?

I've been living my entire life with a feeling that I was destined for something important. Everyday I wake up and find myself waiting for this destiny that has yet to come around. Am I just deluding myself? I don't have many friends but that's ok by me because I feel like I have been chosen for something, but do not know what it is. I ask God for help but never get any answers or even symbolic answers in my dreams. Am I waiting for something that will never happen or is this the construct of a psychological condition?
