"I will not go back no matter the situation"

I do not ever go to the hospital unless it's an absolute emergency which this time it was. I had a kidney infection in both kidneys and after three different sets of antibiotics I was only getting more unwell and the nurse from the walk in centre told me to go to the hospital if the last ones didn't work and after much convincing from my flat mate I went to A&E with a little bit of hesitation. When we walked in to A&E we saw a charge nurse and explained to them why we came and the charge nurse shouted at me and abruptly asked me twice why I was there in such a nasty tone. After the second time I nearly burst into tears because I was in so much pain and felt really unwell. The charge nurse then gave me a note that said I had a uti and at that moment I said to my flat mate let's just go home because I felt like I was doing something wrong asking for medical help when I felt seriously ill. We got to the reception of the urgent care centre to be spoken to abruptly once again by a receptionist. I didn't understand what I had done wrong to be treated this way way as I do not make a habit of going to the hospital. The nurses and doctors in the urgent care centre were nice apart from some nurses standing drinking coffee and playing on there phones and having a good old laugh with each other in side the reception area. After I got taken to Easton ward the nurses were lovely and the doctors were great to. I got told by the doctor that discharged me that I done the right thing going to the hospital because I needed antibiotics that where for severe infections and certain strains of bacteria and they seen how ill I was. I could understand if I was one of the people who go up to A&E every week with pathetic excuses but I never go to hospital ever.
