Doctor think i am lying

Hi
I need advice so after a traumatic event I started to struggle with my speech. I actually had an argument with my husband and after that my speech started to get worse. I now struggle as sometimes due to anxiety words don’t come out of my mouth. I went to my old GP in Liverpool and she said it’s due to anxiety. After few months I moved to a new town and when to see this new GP he didn’t have my medical records. I was struggling to speak due to my speech problem and he said you have no speech issues. He then called another GP who said I have speech issues and he referred me to a Neurologist. This GP who shouted at me kept asking me who diagnosed me with this condition he then asked where I work and I told him he then said do you actually work there?
One of my medication was out of date so I showed him and he said who prescribed you this? I said my old GP he was then sending my prescription to a pharmacy and I wanted a printed prescription so I could get from the pharmacy near my work.
This GP made me cry I was crying when he forced me to speak in mother tongue and I was struggling.
