Put yourself out there. Try to ignore that fear of rejection. You still have trouble believing this, but people like you more than you think.

You're going to miss the deadline to apply for your first choice of university. Don't worry about it. You choose one that wasn't even on your radar, and it makes you way happier than you would have been otherwise.

Try not to waste so much time. Do things that actually make you happy.

Things are going to be tough sometimes, and it might feel like they'll never get better. But you're here now, and that's what's important.
