Questions about jaw misalignment (Photo)

So, recently, I've been getting called ugly. Now, this hurts obviously, especially since I thought I was attractive, but, I'm seeing what they mean. My face is very asymmetrical. My chin is angled to one side, I have a crooked nose/deviated septum, my midline is off, and my lips don't line up with my nose. Also, in resting position, my lower teeth fit behind my upper ones. So, my question is this; are these all related? What would fix them? How much would it cost? Just wondering. Very depressed.
