This is simple practical advice to help individuals dealing with their current problems. I’m not suggesting the nhs is ok or anything:

Speak to your GP and ask to be referred to a provider under the ‘Right To Choose’ scheme. You might be unlucky again, but I know for certain that people in another area of the country with extremely poor healthcare got assessed (via various forms and an online assessment - so local availability of services might not be a problem) in around about a year.
