Some adolescents and adults may have spent their whole lives not realizing that many of their experiences or challenges faced are related to signs of autism. For many autistic teens and adults, going through life without a diagnosis may feel like trying to fit a square peg into a round hole since trying to live by standards made for non-neurodivergent people can be quite tricky and result in low self-esteem, poor motivation, social isolation, and anxiousness. Diagnosis can also help a person to better understand themselves and make sense of their life history.
