Believe it. As much as it sucks, it is illegal, it is their house, and I am pretty sure they support you so you are stuck between a rock and a hard place. Many of us have been there before. I was never threathened with getting kicked out but I had a job by 15 and was a straight A student so it was a cat and mouse game. I smoked, they knew, I tried to hide it, they tried to catch me. It isn't hard to believe.

Quit for a while, work on the temper, and then maybe you can start back up.
