I love self-deprecating humor because every single joke is a high-stakes game of “funny or not funny?” If no one laughs, guess what. You’re now in group therapy with the people who heard you. If, however, everyone laughs, you’ve seen the light in the darkness. Of course, that light is either people commiserating with you or your life is so sad they’re laughing at you. Who’s to say? Funny dark memes can help you either way.
I once visited a doctor who told me that self-deprecation should be wielded like a sword. It’s meant to disarm others, not as an excuse to attack yourself. You’re better than that. Get comfortable in your own skin, and then laugh at the person you were once, not the person you are now. Well, you can laugh at yourself now also, but don’t let it get you down.
