Playing catch-up for ex-essex weirdo

Why was I put back a year at junior school? My headmistress at the school decided to keep me and a girl back 1 year as felt we were not listening in the classroom. This affected me most of my  life as I was playing catch-up at secondary school onward. I think this is what makes me feel insecure or paranoid. I have done stuff wrong and keep being annoying by asking if I have done stuff wrong.
