Life problems

 I struggle to breathe, looking for an exit. My heart beating hard past the breaking point, I try to swim for the surface but there is no escaping pain. I know I'm not drowning, I'm not even in water... but it feels so much like I am. My brain rushes through thoughts, and my heart gives into the pain. I collapse into the endless sadness, the hole without a bottom, the tunnel without an end. Yet I keep on looking for the light at the end of the tunnel, tripping on the rocks. I finally reach its end, the light seemingly coming closer as I run to it. I hear a long noise and watch as the train approaches me, I turn to run but life hits me with its worst blow. I lay on the railroad, staring up at my thoughts, everything that's happened. I feel my body give in, and my mind as well give up. I may have as well gone through this... it feels as if I had. A problem tripping me every time like a rock, running in the darkness. Then the train - worst thing hits me and I collapse.
