Another quite useful and healthy outlet for anger is writing. Even if you “can’t write.” Because actually, if you can speak, you can write. It’s just a period of adjustment using your fingers instead of your mouth. But if you write – or type – exactly what you’re thinking, without even a single change, when you read it, whatever you wrote will sound like you, talking. That’s writing. No MFA required. Especially if what you’re going to write is a letter.
