Who identified your condition?

well first i identified it myself at twelve, but was too scared to find out i actually was autistic so i repressed it. Didn't even think about it up until the last months of high school, where a few friends just straight up asked "are you on the spectrum?" and one in particular, my best friend, also thought i was autistic. At one time, after one of the most distressing periods of my life also my brother said he thought i had autism. That's when i decided to get to the bottom of it and see if i had it (and yes i did, also ADHD)
