My EMDR therapist is not listening to me

I got diagnosed with PTSD during the first lockdown due to me being abused into being more neurotypical in school and college, homophobic behaviour from a sexual health professional and other types of abuse in school and college (both special school and mainstream).

I am currently having EMDR therapy but I do not enjoy it, I always dread the sessions and I find it really hard even though I have agreed to 4 more sessions as I've already had 6 and already want to stop. 

Why? Because the therapist is denying I have an intellectual disability (when part of the abuse was to get me to use advanced language skills that I still don't understand), they are giving me 'function labels' when they should know that is damaging, saying I don't appear autistic when I don't even mask and saying I'm very good at 'processing' when I'm really struggling with it . I am very disgusted by what they have been saying, I feel let down, not listened to and I never thought a therapist would be so judgemental. I feel they are not helping me. 

I might be made redundant from my job due to covid which I did tell them about but they said supported employment services are 'not appropriate' because they're denying I have learning difficulties  and truth be told, Mencap's employment support services helped me get my current job so I personally don't agree with them. 

I really don't want to do it anymore, maybe I'm being 'function labelled' because I am too nice. I maybe need a different therapist, all they're doing is making my life so depressing. 

Please help, I don't know what to say to them.
