If you're stressed, try to take breaks. If you feel like you can't do everything at once and you're multitasking, only tackle one thing at a time. Sometimes, you need to disconnect. So if you can't sleep at night, lie down, close your eyes, then try breathing in for 4 seconds, holding your breath for 5 seconds, and exhaling for 8 seconds. Do that a few times and you'll be sleeping soundly. Otherwise, ask for help. Tell your parents you're stressed and get help from a professional, like a counselor or a psychiatrist.
