There is a lot of practical advice above and I hope some of it helps. It is awful to be in this situation, unable to do the most basic things.
I would phone your GP and ask to see the duty doctor, they probably have one for emergencies and as you are unable to care for yourself, this is an emergency.
Could you have a phone consultation with your GP?
There is a walk in GP centre in the next town to where I live, anyone can go there and be seen (after a wait), is there something similar near you.
I fell and hurt my shoulder on a Sat night in March, couldn't move my arm from my side, maybe should have gone to A&E, didn't because (1) I thought it was bruising and would go away (2) Sat night in A&E - no way.
Several days later I phone my GP, got an appointment in a months time. A couple of days after this I was so desperate I phoned the NHS number 111 to ask if it was worthwhile me going to a walk-in centre or to A&E, they said that my surgery had to see me within 3 days and that they would contact them to inform them of this. My own GP phoned me the same day, arranged for me to see the duty doctor the same day, she gave me strong anti-inflammatories and arranged for X-Rays. After X-Rays I was referred to a physio.
Maybe consider phoning 111 (non-emergency NHS number) if you cannot get to see a GP in the next day or so.
