Tunnel

Sometime I just feel like I live in a dark tunnel. It's so dark that I cannot see anything and I don't know where to go. I try so hard to look for a hint of light at the end of the tunnel to lead my way out, but unfortunately I can see nothing. I fumble and fall, try very hard to get out, but all I get is just the bruise from hitting my head on the wall. I'm still in the same spot, not getting anywhere. Will you help me?
