Fed up - computer says no (assessment result - not autistic)

I don't know where I'm going with this but I don't know where else to take this.

I'm an adult female who has just received a 'not enough evidence for autism' result through NHS assessment. Reasoning being that I didn't score high enough on their criteria. When looking at the criteria though it seems a little outdated. When looking at other resources it's pretty obvious to me that I'm highly likely to be autistic, with ADHD thrown in for fun. However, I didn't fidget enough on camera (which didn't show my leg bouncing the entire session), I don't have fixed interest (I flit because I easily lose interest and get attracted by all the other amazing things that fascinate me), I have good social skills (the assessor had a pet, of course I was going to say hi to the animal?). 

Recommendations are to go back to counselling (10 years and counting), increase my anti-depressants and basically continue with everything that makes life harder than it needs to be. 

I feel so undermined and mis-heard about this. Local services and support are only accessible with diagnosis, my manager doesn't know how they can help and doesn't want to use me as some kind of guinea pig in case it makes things harder.

I knew it would be a battle when I began this process in 2019 but I feel a lot flatter than I thought I would.

Thanks in advance for any advice or response.
