UK: AuDHD and OCD. Didn't get help from ERP (CBT) Thinking of EMDR therapy. (Pure-O and Real Event OCD)

I tried CBT/ ERP multiple time with no-benefit. I have AuDHD and OCD. (Autism and ADHD) I probably have CPTSD too from trauma

My OCD is pure-O and Real Event-OCD; so kinda atypical-OCD :/

UK NHS Exposure and response prevention therapy seems the only therapy offered for OCD. I wish alternatives existed; ERP is CBT and potentially Neurodivergent people don't always get much relief from it. I know others that found it didn't help. Its the "gold standard" but if it doesn't or can't help you the medical service feels like it gaslights you into feeling lazy or just offers more of the same! It takes ages on the NHS. I had a remission window and then it came back with a vengeance! My life is pretty much 24/7 enslaved to OCD

I'm thinking of looking into EMDR. Similarly diagnosed (autistic, AuDHD and OCD) ND friends and acquaintances have recommended it; it might get to the root rather than the symptoms, thoughts? ERP felt formulaic and it didn't really go deep into my OCD "trauma"

Pure-O and Real Event OCD is an horrible combination! Any thoughts on EMDR therapy from anyone Neurodivergent with OCD? I'd appreciate insights!
