I'm on the spectrum and also have Menieres which affects my balance. I joined some of the ESA/DLA facebook groups and got some good advice. When my appointment came 3 years ago, I requested a home visit as I had difficulties leaving the house and an audio recording of the interview. I got placed in the support group and am still waiting on the interview. I think they gave up as it was made difficult for them. My advice is to join some of those groups, I got some great advice. You might find yourself having to appeal, they have a habit of failing everyone first time around.
