I've never done nor plan to do sh, though sometimes when bored I want to do it, though it normally goes away after a small amount of time. I never plan on doing it, though sometimes I rub things or scratch my thighs hard to somewhat represent doing it. And I always feel bad because I feel as if I'm mocking or making fun of people, like my life is fine, yet I feel like doing it since I'm imbored, and the more I think of the way people actually struggle with sh just makes me feel worst.
