Answer:
Taking a nap after class
Explanation:
Calling a friend might help you to vent. Talking about all that is bothering you is a great way to feel at least slightly better about something.
Going for a run is very beneficial as well. So are meditating and breathing exercises. All of those might take your mind out of a bad thing in the correct way and spend your energy in a beneficial way.
Taking a nap after class is very unlikely going to help you at all. Instead, you are most likely going to keep your mind in the thing that is upsetting or stressing you. Also, it might help you to only internalize your stress instead of dealing with it.
