I was 12 when I was diagnosed. I suspected nothing before then because I was young and didn't know about mental conditions. I have always known I was different however and used to say at age 10 and 11 what was wrong with me and how I wish I could trade my brain for a new one. I had tons of labels back then; sensory processing disorder, suspected OCD, cluttering disorder, language processing disorder, communication disorder, dyspraxia, ADD, and they mentioned I had poor social skills.
