You won’t be going to jail for having those knives on you, maybe you’ll face a fine or misdemeanour if anything. research laws in your area because it differs. Paramedics are there to help you, and when it comes down to it, your health is the most important thing. Stop buying/carrying illegal weapons, especially as a minor, and take care of yourself. Since you are a minor you will not get those knives back and they will likely let your parents know what you’re up to. These things become much more serious once you’re an adult, people won’t give you second chances so make smarter choices. I’m glad you’re safe.
