You said: "I've been here since 2012, and I've never felt like I wasn't just about to be fired."

Imagine someone terrified of having a car accident every time they drove. "Have you ever been in an accident?" "No, never."

Or someone constantly worried about having left the oven on at home, so much so that they have to check it multiple before they leave. But they've never actually left it on.

This isn't an attack or a criticism, but sometimes it can be difficult to notice our own unhelpful patterns of thoughts, even though we'd notice them straightaway in others.
