I've w got always had narcissistic traits. Constantly throughout my preteen years, my mom was always calling me self centered and telling me that "the world doesn't revolve around you". It started getting more severe around 14 when I went to teen drug rehab and people were voting for me to go level up. This one kid didn't vote for me because I was "dramatic" and "acted like my problems are worse than other people". I got really mad, tore the ballot up and plotted revenge.

I was diagnosed under 18, even though they shouldn't do that.

How old were you when you started realizing that something was different, or when were you were diagnosed?
