Diagnosed at 47, wish I didn’t know

Hi everyone, I’m a 47 year old woman who was diagnosed with autism and adhd through right to choose around 5 months ago.

I feel like I wish I didn’t know I was autistic. It was a huge shock to me. I was only diagnosed because my GP suggested I might have ADHD and part of the assessment process included autism tests. 

No support was given after diagnosis. They said they’d send info but I haven’t even received my report yet. 

Ever since I’ve been diagnosed I’ve felt extremely paranoid about any interactions with other people. I’m really struggling. I can’t seem to find anywhere to get support. Does anyone know of support groups for late diagnosed people? I live in east London. Thank you.
