Glitch180's "I'm Sick Of It" is about the harsh voice in your own head that tells you you're not good enough. The speaker is worn out by it. They describe holding back tears and cries for fear of looking weak, and say that the one time they did make a sound, it almost destroyed them.
The poem's main idea is a courtroom. The inner voice acts like a prosecutor, building a "valid case" against the speaker and calling other people as witnesses, though the speaker points out they aren't under oath and may just be protecting themselves. The voice even invents evidence and digs up "past records," focusing only on wrongs. By the end, the speaker can't recall doing anything good and half believes the voice is right, because no one ever argues back.
The mood is tired, bitter, and quietly sad. A hint of dark humor ("It's very creative actually") makes the despair feel more real.
