It cant get any worse

I need help. I’m a 16-year-old boy. My parents are making me take an anti-anxiety medication even though I don’t want to. It makes me feel sick I get a racing heart, my vision is worse, and I’m so constantly tired that I can’t even use my computer. I also have panic attacks, and they know it. But they want me to keep taking it because I treated them badly a few months ago. That was just a phase, because I was very lonely and now they’ve ruined my life. What should I do?
