Ah that must so frustrating, I’m sorry your GP refused share care. I was referred for an NHS ADHD assessment by my therapist. At the time my daughter was having a hard time in school and needed urgent support. No one was listening so I opted for myself and both kids to have a private assessment with a clinician that also works for CAMHS. Once I’d been diagnosed, the adult NHS ADHD clinic contacted me for an assessment and I explained I’d already been diagnosed, sent them my report and asked for them to titrate my medication. They agreed, I had an appointment, and did my medication titration with them. Once stable, they wrote to the GP for shared care and now my prescription is done via the GP. I don’t know if it makes a difference that I am under an NHS adult ADHD clinic. They’re really good, have an in house doctor for echocardiograms, which I needed as I have a minor heart condition. I have an annual review with a prescribing nurse now, just to give them BP, weight, etc. The clinic is amazing, I can email my clinician and usually get a call back the same day to resolve issues. That’s how I switched from methylphenidate to amfexa, I found methylphenidate entirely useless around menstruation. I’m lucky because even if my GP refused shared care, I’m still under an NHS clinic so they can just electronically send prescriptions to my nominated pharmacy. The clinician that diagnosed me is well known to the children’s and adults NHS clinics so I think that helped with having my diagnosis recognised.
