Hitoribocchi no Marumaru Seikatsu S01

Hitori Bocchi suffers from social anxiety. She's not good at talking to people. Her actions are really extreme. She's an expert at avoiding people. If she overdoes it, her legs cramp up. When she's alone, she becomes very selfish. If she's under too much stress, she throws up. And ideas often come to her mind quickly. Now she's entering middle school and her only friend, Yawara Kai, is going to a different school. This makes Bocchi all alone. In order for Kai to talk to her again, Bocchi must make friends with one of her new classmates.
