Ok, take a step back and breath. Then go and read this article on vectors:

Euclidean vector - Wikipedia, the free encyclopedia
Now after you have read that article, say you have a position (10, 10) and you are looking along the vector (1, 0) (will refer to this as the look vector). What this tells you is that you are facing straight down the x-axis at the point (10, 10) only. This has no relation whatsoever to do with velocity or movement direction.

Facing down, does it not mean i am looking right? to look left i would have to do (-1,0)
