What is this feeling?

I can't eat, I can't sleep. I am very tired, every part of my body is asking me to rest. But when I lie on my bed, my brain enters hyper-drive and I just start thinking about the so many things that we have no answers to.

I want to sleep, but I just can't. Why?

I know you're reading this. But try not to talk to me. I want you to be able to come to terms with what you're really feeling, whether it is something only for the moment. I know it's killing you, because that's exactly how I'm feeling. But I do want you to make a decision that you will not regret in the future.
