Sounds like you’re juggling way more than most people your age, and it makes sense that everything feels tight right now. Three major works on top of demanding subjects, a part-time job, social life, and the pressure of moving into Year 12 would stretch anyone. No wonder you’re feeling the weight of it.
When life gets that full, having even a small pocket of time that’s just yours becomes important. For me, that ended up being sports betting as a casual hobby — not heavy stuff, just a way to unwind after study sessions. I treated it like checking match stats, following team form, and making tiny friendly wagers the same way someone else might follow a TV series. It helped me disconnect from school stress for a few minutes without feeling like I was wasting time.
About your actual situation: taking a break over the summer sounds smart. Distance often helps you see which commitments are feeding you and which are just draining you. As for the job, you don’t need to decide today. A lot of students step back or reduce shifts during high-pressure periods. Quitting isn’t the only option — a conversation about fewer hours might free up breathing room without cutting off income entirely.
Ask yourself two questions during your holiday break:
What actually supports me right now?
What do I only push through because I feel like I “should”?
If the job sits firmly in the second category after you’ve rested, then letting it go to focus on your major works and wellbeing is completely valid.
You’re clearly capable — your subjects prove that — but even capable people need space. If something has to give, it’s okay for it not to be you.
