Lots to unpack here for yourself. Don’t make any decisions until you’ve had a chance to breathe and mull over for a few days. It almost sounds like you got overwhelmed on the day, went into panic mode, felt like a failure and that the only solution was to quit immediately. Maybe teaching is your path and worth pursuing, or maybe it isn’t. The student behaviour issues are very real and lots of teachers struggle. But lots also feel it’s rewarding despite the challenges.Take some time, talk to people around you, see what you feel like after the adrenaline has settled. No one is perfect at something first time they do it.
