"think I must have triggered some sort of universal connection to someone because my appointment has been moved to next week "
Excellent update. Well done that GP. 
Ideally though you shouldn't have had this worry in the first place first place and no I bloody well don't think that is asking too much. And that's down to NHS workforce planning and investment. We need a workforce fit to work therefore health needs to be top of the government agenda.
I'm at the stage where I think the current government is just getting in the damn way. Another 12 months of juvenile campaigning (meat tax, 7 bins, forced carpooling) rather than actual governance and God knows where we will be.
