Becoming Symptomatic

When did you guys start noticing your behavior? Did smth trigger it, did you have a moment of awareness, were you told? How old were you? Was it a slow realization or did it hit you all at once? What specific symptoms and traits were like a lightbulb for you or obvious from the get-go?

Just curious because it was pretty recent that I've noticed my odd behavior and concerning thinking patterns, how disconcerting my mental state really is and that I'm not being dramatic or a "main character". I want to know the when, how, and why for you guys as well if you're willing to share!
