Adult Autism and Jobs

Hi, I’m 20 years old female and I am waiting for a referral to be assessed for Autism. When I told my mum and dad this, they are very against me getting the diagnosis because they say that if I do get diagnosed (as high functioning autism) as soon as an employer sees that I’m autistic I will ‘go straight to bottom of pile’. And that I won’t pass medicals for the jobs as it will say autistic on my records. I work in theatre as a dresser / stage crew. I’m worried that if I do I won’t get jobs as the stereotype of autism is not be able to talk to people, (I do talk, I just mask what’s going on inside my head).

 Has anyone been that they know of discriminated against because of their autism? 

And do you think I should still get a diagnosis?
