1. Yes. I said that I have nothing to do there, I don't see the point of coming just to hangout. The reply was that they'll find something for me to do. The manager took it as their fault, as if if they're unable to find work for everyone until they collapse on the couch they're not doing their job.
2. No. I hate it.
3. I don't mind being fired. If I work 40hrs/wk I'll keep getting terrorized with voicemails and text messages in the evening and on weekend. It sucks.
4. I signed up for a bunch of art classes at colleges in the evening, but quitting will allow me to expand that into day as well.
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.
