It's going to suck.
I'm not gonna lie and say that next year is going to be lighthearted and fun, because it's not. You know better than that. Most of the time, you'll only have yourself to blame and you'll be the only one helping yourself back up.
So just a few pieces of advice for the coming year:
College dreams will be crushed and remade from the dust, so make sure you don't lose hope. It may seem like a huge leap, which it is, but you're totally capable. Give yourself pep talks of the most reinvigorating kind. Remember that the more positivity you put bring into the world, the more positivity you will get out of it.
It'll be overwhelming when you have to do things. It's easy to put them off. But just do them. Make it easier on yourself and lift those heavy errands from your shoulders. Once you're done, you'll feel better than you did before.
Make time for yourself. Your health is important and without it, you can't do much else. Keep time to yourself sacred, take care of your body, and give it time to heal from scars of all kinds. Forgive yourself. No amount of forgiveness from others can substitute the apologies you owe to yourself.
Try to be happy, even if you feign it. You won't be feigning it for long.
It'll suck, but it will be worth it.
