Struggling with OCD and Autism - Need Help!

I'm 39f in south east England. My OCD is terrible, it's got worse over the years (tried all sorts of medication - hate them). I got diagnosed autistic (and ADHD) last year and one day read an article about how exposure therapy can actually be harmful for Autists. It explains so much because I would be following therapists advice and forcing myself into situations I wasn't comfortable with, and end up with events that made me more traumatised. I kept getting worse and thought I was 'failing' therapy. I've been trying to deal with it on my own for a while now but feel like I'm at the end of my rope (and autistic burnout). Does anyone know if there are specific therapists/help out there for people with OCD who are also autistic? I desperately need help but can't go through talking to another person who doesn't understand and just follows the 'OCD textbook'.
