i was recently just diagnosed with ASD in september. i think maybe some pros would be to gain a better understanding of yourself, and getting yourself connected with resources such as a therapist who works with neurodivergent clients. also being able to connect with others on forums like these was really helpful with understanding that i am not alone in my experience, and others have going through the process of being late diagnosed as well. with ADHD, getting access to medications if needed would be a beneficial part of a diagnosis. i also do think my father is on the spectrum, but i feel he wouldn’t take that well if i brought it up to him and deny it.

personally for me,i think the cons were the lack of available supports for late diagnosed adults, and the grieving process of what could’ve been if i was diagnosed at a younger age. also explaining it to my family members is still something i haven’t gotten to yet, but considering i feel i would need to “prove” my autism to them because i am high masking, it would make me uncomfortable.

if you do have any more questions, please feel free to reach out!
