Little steps!! It’s totally normal to freak, I mean, you took a leap! Every call, things will change little by little. Can you possibly work part time so it doesn’t overwhelm you while you get used to this?

So sorry you had this experience while trying to work at a call center. So I've been working in call center environments for most of my career I was also an electrical engineer. For phone anxiety...it's easy to get flustered and panic. One trick I always find helpful is to pretend that the person I'm speaking to is someone I know. It takes the pressure off...also they may tell you that you have to follow a script, however if you make it your own and stick as close to the information in the script as possible you will sound more confident and be more comfortable in your communication...if a call center environment is what you need for health reasons then try again and just remember to take your time and only do what makes you proud to do it...if outbound calls or sales calls aren't your thing (they aren't mine and I don't take those jobs...I have found most want you to do things that are unethical) don't do anything that upsets you or goes against your values. If you decide you want more tips on how to do that kind of job let me know.
