It's really shocking the way autism was missed for a lot of women in our generation. A diagnosis wouldn't change a lot at this point (it would have been SO helpful when I was struggling in university and couldn't figure out why - mainly social issues), but it could be good for the times when communicating can be a challenge.
My friend , finally got an Aspergers diagnosis after a few years of the waiting game too. I imagine she's about the same age as you (based upon things you have posted). Having the diagnosis has made a big difference already to her (socially, communication, etc)
Likewise, I had another friend diagnosed with Aspergers later in his life and he was so happy to have a diagnosis, because it explained everything in his life.
