Your negative feelings are valid, because all feelings are valid, but they can distort your beliefs and behavior when you don’t give enough consideration to alternatives.
When you think I bet nobody really likes me, they’re probably just tolerating me to be polite, also ask How can I let the people around me know that I genuinely like them?
When you think I’m so lazy and unproductive, also ask What’s one small but useful thing I can get done in the next hour?
When you think The FBI agent assigned to me must think I’m such a loser, also ask How can I radicalize my FBI agent?
This is the kind of mental health advice we can all use.
