I hear you about having to add duties without a raise or any appreciation. And the psycho boss. (you don't work where I do, do you?) Congrats on making a very difficult decision, but if you're not happy there, it will be for the best. Always keep what you want to do in front of you, and if you get discouraged, remember what you're escaping from.
Good luck!
