Annual New Year's Resolution advice from your local internet auntie who successfully turned around a lot of problems:

That list of fourteen resolutions you have? To stop forgetting to brush your teeth, to lose weight, to stay atop your homework? Which ONE SINGLE CHANGE would have the most immediate, day-to-day effect on your mental well-being? What would give you more spoons to tackle the rest?

ONE RESOLUTION AT A TIME. If you try to change fourteen things about your life at once, you'll get overwhelmed and give up within a matter of days and convince yourself you're not strong enough to change. But you are; the trick is to change ONE THING AT A TIME and focus on it until it's become easy.

If you have something sleep-related on the list... you should probably start there. Sabotaging yourself by staying up late is an extremely common problem among the type of person likely to be reading this post. Learning to Stop Doing That will make sorting out the rest of your life magically so much easier.
