"Flu jab"

Seen the Doctor about seriously breathing problems I have in the flu months and suffering with severe sleep apnea and the other day suddenly waken up and gasping for air and we almost had to call the ambulance services after few minutes not getting enough air into my lungs. Like every year getting the flu jab what is a must for me to minimise the flu to avoid to getting a blocked nose due to my sleep apnea what turns into a seriously panic attack what I explained to my Dr and he wants me to see the respiratory clinic again but cannot get an appointment at all. I told my DR I am getting the next day the flu jab from the GP surgery what was already running late for me what worried me sick and not being vaccinated for Covid19 due to severe health problems I suffer with. 18.50 got a phone call from the GP surgery telling me my appointment is cancelled due not having any flu jabs but for my partner they have and they were seeing just before me. They cannot even tell me when they have jabs again and been told I need to phone in to find out what I cannot do and I ask them to phone me when they jabs again and book an appointment but I was told They cannot do that. Why phoning so late in the day to tell me they run out so they told me when they could see that during the day and let people in plenty of time and the surgery should known I depend on it after even seen the DR only few hours beforehand. Where is the logic or planning? This is putting severe stress on my mental health condition but the phone operator had no clue how to deal with my situation. I turned real mad, so British.
