If I had taken up what you are doing in my parent's home, I would have been out on my butt immediately. I would not accept that kind of activity in my own home from my own children either. It IS that simple. You are in her house. You need to take these activities out of her house. Get a different job to earn the money in the meantime, or simply move out now, but don't expect your mother to condone that kind of business in her own home.
