It sounds like she doesn't trust you to respect other people's property. If you gave her a reason to think you might eat food that isn't yours, or use someone's things carelessly or without permission, then now you get to live with the consequences that you caused. I suggest you don't escalate, or the next consequence might be you having to move out.
Edit: After thinking about it, I realize my answer probably wasn't helpful enough. I do think you need to avoid escalating, but as you are angry, you might want pointers how to do that. I suggest: Take up a form of exercise that you can do by yourself, which you do away from home. It may be power walking in the park, or power lifting at a gym, or swinging at balls in a batting cage, or anything you think works best for you. The advantages of this is you can work off your aggressive energy in a non destructive way, while simultaneously giving you and the people you live with a break from each other.
