Fretting about the validity of a private diagnosis

Hi,

After the helpful responses on my last post I've started down the route of self-referral to our local NHS service. But I'm also really tempted given the long wait to book a private appointment. But I can't shake the idea that I'm basically paying someone to give me the answer I want that I'm autistic. Has anyone else struggled with this? What did you decide in the end? I recognise I'm lucky to be able to choose.

Thanks
