Been there, done that. 1st off you have a chemistry problem in your brain. Not your mind your brain. This is a chemical imbalance that can be readjusted. A good 1st move is to printout a copy of your post here and hand it to a doctor. They have the antidepressants that will reset the brain's balance. You haven't done anything wrong and there are many people that are in your situation. We over-pressure ourselves creating a continuous stress that wears the brain down. When it happened to me the world actually turned grey. Amazing. You'll come out of this and then one day you'll be making a post that will help someone else. Oh,one other thing. About quitting that job, good for you. You have courage to speak your mind, that's a rare thing nowadays. You still have your skill-set and something better is just ahead.
