You should quit immediately. Also, please see cperciva's comment above. Take a complete break for one full week, before making the next move. That will help you take a better decision on what to do the next. Go and meet deep personal friends, you'll need them while you decompress your mind. After that, start networking like a maniac, showcase your skills in communicating with {people,computers}. While you're searching for the next job, it is a great help to be a part-time faculty at a computer institute. Good luck.
