Questioning My Sanity

Aside from being a pretty decent song by the female punk metal band "L7", that's sort of the way I feel right now. Imagine, if you will, a square. Like a floor tile. Twelve inches by twelve inches. You're standing on it. You're in the middle of a cavernous room, surrounded by a lot of nothing, except for the aforementioned "cavern". You can't see the floor, you can faintly see something in any direction except directly behind you. If you turn around and look directly behind you, a very clear, easy to follow path of other 12x12 tiles maps out where you have been. Other than that, there is no floor. Sconces cast their flickering light on the cavern walls all around you, what little of them you can see. You know, beyond a shadow of doubt you want to go forward, not at all interested in going back, but you have no idea how to take the next step. You see, an indeterminate distance away, a safe haven, a very appealing looking ledge with good cover and protection from the cavern air. A good place to set up camp for a while. You want to get to that destination. But how? Or maybe you know you want to take a chance on getting to any of the cavern walls you can faintly see in the distance, in any direction, but how? The only two things for certain are you definitely don't want to stay where you are any longer, and you don't want to go back where you have been. The desire to go forward, to be in any location other than where you currently are is so powerful, it feels like a physical thing, taking up space somewhere in the middle of your chest. So what are you supposed to do? If you look directly forward, in front of the tile on which you are standing, all you see is pitch black. You have no idea what will happen if you take that timid next step. How are you supposed to step confidently on to absolute uncertainty? So, if you can't figure out how to move forward, you can't go back, currently your only option is to stand where you are, what then is the point? Where is the logic in continuing that stagnate existence? What functional purpose does it serve to continue on, standing on that one tile? The answer is, of course, that in this hypothetical scenario, there would be absolutely no reason to continue on. If you can't figure out how to go forward, going back is not an option, staying where you are serves absolutely no purpose. No happiness will come of it, no function will be served, no one will be helped. Sometimes I envy people whose deepest thought is (insert inane sports comment here)
