OK, now substantive stuff - I HATE this about GP surgeries. I do not think there is a proper understanding of the extent to which these stupid rules disadvantage those with MH issues. I understand the system is under stress, but there is really no excuse for it!
Once you feel calmer, can I suggest an email to the practice manager? Just a simple, straightforward message that says
'Dear X
I urgently need to see a doctor to discuss some health issues that I have been experiencing. However,
as I do not currently have a GP, this means registering with your service. Yesterday I was informed by your receptionist that I simply needed to drop off a form to register and that I could do this at any time of day. However, I attended this morning to deliver the document, and was abruptly informed by your receptionist that you only register patients between 10.30 and 11.30. (Your forms state that the registration time is 11.30 to 12.30, by the way). The manner in which this was said was rude and abrasive.
I work full-time and I am unable to attend in those hours simply to register. However, I feel very vulnerable and I do need to see a doctor urgently. (The distress that the receptionist's rudeness and obstructionism has caused me has made me feel significantly worse.)
Please can you let me know how on earth I can register at your practice in order to get the medical care that I urgently need?'
A decent manager will get back to you and sort this out straight away.
