Sorry to hear about this. I know what it's like to have a sister (mines older but still immature) who knows exactly how to push your buttons. It's extremely irritating. I don't know how I can tell you to fix this but I think over time, things will settle. When time passes, she will mature, and you will also mature. You guys won't be fighting about the same things that you do now and HOPEFULLY she learns to make better choices. I am sure things will settle with time. As for right now, I am not sure. I don't know if talking to her or your parents will fuel the fire. What really worked for me and my sister was after we got a bit older, I told her how I felt inside. I felt vulnerable. It felt very odd to open up to her. Maybe if you talk to your sister, she might not care which can backfire and piss you off. But hopefully she can understand you. Do this at a time where you guys both are happy so that things don't get as heated.
Best of luck. I wish you the best xoxo
