Why

Why my heart is so in pain? I was awaken by the pain. Don't understand. Yesterday I was so tired and I shall have a fine sleep. But the reality was that the exhausting activities help little in sleep quality. My mind was like having a ride in a wild forests. No destination. The mind went with the full speed. Yesterday I heard an opinion. Someone would rather being killed by bumgee jumping than by sky diving. He said the memory rewire part would be killing. This morning, the thought came to my mind and I understood why he said so. Since I was awaken by the pain, my mind keeps rewiring things. It did kill me slowly. I don't like when my mind behaves like a free bird.
