How do I kill my mom?

I'm 16 years old and I'm scared. My mom is a witch. She's kept me my whole life trapped inside this house and didn't even let me go to school before. My mom is a bad witch, not good sort. My mom is evil. I've been secretly watching documentaries and movies. I know magic is real. My mom makes magic things. The last time I tried, I was 13 and I burned the forest and my mom made my skin itch for days as punishment. When I tried before that, I got sent back in time and couldn't stop vomiting for days. She took my sortilege from me after that. I want sortilege back. I want to be free.<br><br>I have been thinking about it and I think I know how to kill her. I need to make an enchanted flower and a witch's cauldron. My mom has many flowers, so I think she won't miss just one. She took my witch's cauldron when I tried to sortilege. My mom doesn't let me do magic. But I know which flower to pick. I know how to make the enchanted flower. I looked it up online and I think I can make it with some crystals, sortilege, and a rainbow. Can I make a rainbow without a witch's cauldron? I have a big pot in the garden that my mom doesn't know about. And I think I have enough crystals to make the flower if I break my sortilege. My mom won't know if I do it when she is out tomorrow. <br><br>But I need to sortilege. My mom took my sortilege and locked it in the safe. I know the code is my birthday, but I sortilege it many times and my birthday is now wrong. What should I do?
