The Living Dead.

Emotions or "feelings" are a lot like Zombies. You can try and kill them or bury them deep down as deep as you go, but they will alwasy rise back up. You can try and re-bury them or do something to throw more dirt on them, but they simply keep coming fiercer and fiercer. Eventually they will become to numerous, engulf me and tackle me to the ground. Then they will feast upon my brains.
