To give you an idea of what that looks like, I currently have two options to get healthcare. I can try to get a GP appointment. The only way is to phone, and the phone system of my local surgery is overloaded as soon as it opens at 8am. You have to ring repeatedly until you can even get a place in the phone queue, then you stay on hold until you get through to a very stressed receptionist who will see if there are any appointments left. They run out quick, and if there aren't any, you have to try again tomorrow at 8am when the next batch are released.
The other option is to go to A+E. Calling an ambulance is out of the question, because there's a good chance you'll die before one turns up (if you actually have a life-threatening emergency).
Good job we saved the NHS, eh? Covid won't kill granny, good ol' neglect will.
