People who found out they had autism in their adult years

What made you get diagnosed? Or even realize that there was something "different"(i'm sorry if this isn't the right word) about you. I've been struggling with this thought for a couple years now, but i'm honestly not sure if i'm just being paranoid and finding traits similar to normal everyday things OR if it's something I should seriously take into consideration.

EDIT: Thank you everyone for your responses. It's been mostly informative and a little overwhelming. A lot of your stories seem to match similarities in my day-to-day life and has given me a little more confidence to bring it up with my Dr
