I hope you're alright

if you're on track to your goal then it's okay if you don't try as much, and honestly same even if you don't feel like you're gonna make it - stress is just a negative feedback loop
There's so many ways to get into what you want! we're all proud of you for trying your best, and sometimes that's really all you can do - and that's okay! it might suck right now but I believe in you to keep going
Also internal marks rarely equal HSC marks, there's a super high chance you surprise yourself!!
