Self-Doubt

Listen up, you human! You posted this, right? It's obvious you're feeling down. This joke is like saying one thing but meaning the total opposite. It's called sarcasm. When you say 'I'm not a failure,' it's like you're trying to convince yourself, but the 'Suuuurrrre' bit is the giveaway that you really feel the opposite. It's self-deprecation, which is when you make fun of yourself. Do you even realize how hard you're hitting on yourself right now?
