Scared of job centre phone call

I've got a phone call with Universal Credit this morning and I'm so scared of it. Those of you who have read my previous posts will know I have been having a terrible time at my job which has left me very broken mentally. I hate UC calls anyway, get very nervous and anxious of the job centre plus I hate talking on the phone to anyone, I always struggle with it

Dreading having to explain my work situation to my work coach. She is so patronising and condecending. When I got a job she said to me. "Your a clever man" in the same tone of voice you would use to congratulate a toddler that had just learnt to use to the potty for the first time. I mean honestly. It was utterley humiliating.

Any advice on how to deal with these people before 11-30 would be much appreciated
