Working for a call centre!

I have recently been working for a call center, due to covid it was a viable option as it was homebased. 

The first week was rough the predicted crash course with fries like any other major corporation. 

I felt stress as I was not trained properly for the job but as the weeks progressed I adapted and learnt on the job, I suppose like everyother person. 

I started to feel really burnt-out at the end of the day and this week past I've been completely exhausted yesterday I had such chest pains that I threw up, my head was sweating and I was dizzy.

Has anyone ever felt like this in a similar role. 

I feel bad, what ever job I do the stress of it alway makes me ill mentally I just push myself through but yesterday I really felt I was going to die, I know that's melodramatic but that how I experienced my situation, plus it being cover incarceration year where I live the doctors surgery isn't even answering the phone not that they did before I suppose.
