I know for many of high schoolers it is a stressful time right now with AP's and other assignments. Just remember to stay calm! Everything will be all right. Just breathe, because soon this will be over and we will be able to have fun and relax.
In the meantime, it is a really good idea to of course study for those APs, but also take some breaks. Go on a walk to give your brain a break.
Maybe try some painting, and if you are not that good of a painter try some paint by numbers. They are super relaxing and they always look super good when they are finished.
You could also watch a TV show like Outerbanks, Grey's Anatomy, and many other shows that have been recently trending. Remember to breathe and stay calm. You got this!
