Confirmation of autism?

So I was meant to have confirmation of either way today which didn't happen (but that's another issue). I am worried about what happens if they turn around and say I don't have autism? I know I should be happy about that but then it means I still don't have an answer for why I can't read social interactions and facial expressions; how I cant even cope with simple tasks; how I cant even hold down a job. Another reason why I'm afraid about it is because what happens then? Will I still be welcome on this site? I am probably overreacting anyway but please let me know. Thanks for listening to my rambling.
