"Poor experience in reception"

I'm a trans femme person who after years of suffering, struggling, dropping out of uni, losing employment etc. finally managed to pursue an ADHD diagnosis. I'm now almost up to the 2 year mark and I understand that everyone is short but have found my experience at reception at the Riverside resource centre after finally receiving a diagnosis and wanting to try medication extremely negative, with the receptionist making me feel like a bother. This was by saying it would be months until I would see a doctor.  When I asked  for a rough estimate I was told again that it would be months.

Today when I called, they were unable to find my record with my chosen name so I begrudgingly used my deadname (it is a foreign name), which they kept mispronouncing even after I  corrected it. I think I can confidently say that I am not the only trans person on their files and surely there must be a better way to go about this than making someone who is struggling enough to seek help (and it's not easy) go through repeating their deadname.

The straw that broke the camel's back was being called sir.  I asked them not to call me sir,  and the  reply was okay sir. This felt either malicious or careless. I am highly anxious about phoning for updates in the first place as I never want to be a bother.  I just want to get on with my life. I ended up phoning in sick to work as a result because the process has been so drawn out and strenuous and this interaction really negatively affected me.

I read in the other comments that there have been other issues with the receptionist so wonder if they might benefit from some more training.  I don't want to get them into bother but today was honestly too much and had me struggling with thoughts of self-harm (I am safe now though but just wanted to emphasise how this has affected me)
