Discouraged

I make earrings as a hobby and also to earn money. Today my mom told me that I wasnt selling any so I shouldn't even bother getting more supplies. I am really disappointed because I can't sell anything because she won't let me go to booths and no one asks me to buy any lately. I wish she hadn't have said something so rude whenever it's partially her fault that I can't sell anymore. I hope they start selling more so that I can keep up my hobby!
