What it means...
That all depends. Were you ever hard on yourself because you didn't have many or any friends? Did you ever belittle yourself because you just didn't get it? Have you never been able to maintain a friendship?
Has anyone ever told you:
It's all in your head.
You can if you just try harder.
You are capable of much more.
You are selfish.
Any sensitivities to food, light, sound or texture that bugged you, and no one else?
There are SO many reasons to get that diagnosis. Now you know why. Now you should accept yourself, and not belittle or berate yourself...and definately NOT let anyone else do it either.
You can reorient your life. You can make your home more sensory friendly, and understand there are situations that you just don't need to put yourself in because as someone with AS, it isn't going to work for you.
Acceptance of self is a difficult path, and this helps you understand yourself in ways you simply couldn't have before you knew.
Take a deep breath, exhale...and just be.
