ASD diagnosis rejected

Hi everyone,

Today I had my feedback from my ASD assessment and i've been told they're not diagnosing me and they think my symptoms are just down to anxiety. 

As you can imagine i'm extremely upset about this and been crying all day as I know deep down that I am autistic after doing nearly 2 years of research reading medical books, listening to podcasts and speaking with other autistic people. They told me to speak to my GP to possibly up my antidepressants and speak to them about anxiety (which i have already been doing for 9 years and they've got me nowhere). I can only imagine this is down to the assessment criteria being so outdated and not suited to late diagnosing autistic women. 

I am now looking at going down the private diagnostic route as I am not happy with my result from the NHS. 

I was just interested to see if anyone on here had any experiences with private ASD diagnosis' (either alone or following from a rejection of NHS diagnosis). Or if there were any recommendations, tips or advice to cheer me up as I dont have many other people to talk about this with so feeling pretty low Disappointed

Thanks in advance !!
