<human>: Can you provide a brief rundown of the text in within 3 sentences?

I'm 17, in my last year of high school, struggling in a class. This leads to a lot of arguments because I did badly last semester and I'm currently working to do better. (Preemptive explanation: I can't drop the class or switch to another one, I checked.) I always end up in these vicious arguments with my parents where I totally lose it because I'm so frustrated and it really is hurting the three of us. More important than the class, I want to treat them right because I really do love them but I just can't handle myself when I get emotional. I yell, cry, etc. and they're sick of it. They are really tired of dealing with me and my outbursts.

BTW I hope this isn't against the rules of this subreddit but I did previously post about this [here] although being an r/catholicism post it was clearly more spiritual-based and this is more of a "concrete advice" request.
<bot>: Getting in arguments with my parents a lot, always getting angry and boiling over. How can I stay calm, and how can I repair my relationship with them?
