Mourning a Late Autism Diagnosis

hii. i got diagnosed in 2020 as well, although i was 15 so not exactly the same haha. i honestly think about this all the time. my brother who is also autistic got diagnosed at 2 and subsequently received the right conditions. i however was left to my own devices. so many things i know in my life could’ve gone better had i been diagnosed as a child. my brother flourished and grew, he got therapy from a young age and learned how to manage the results of being autistic. he was taught and guided, as well were the people around him. i however, suffered immense mental problems and ultimately crashed when i hit 12-13. if it took till i got to my 20’s for a diagnosis i don’t know if i would’ve made it.
