About to quit my job after day 2

About to quit my job after day 2 Hi everyone I’m 2 days into a job and have so far avoided phone calls but it’s a big part of the job and I know I can’t do them. I’m working for a solicitors in the UK and it’s a lot about calling clients to confirm times etc and I can’t even say the name of the firm. Any advice? I’m thinking I’m going to text in the morning and quit. I can’t take any more of it and my anxiety is through the roof. It’s a tiny room with 6 of us in so everyone can hear your every word.
