I've been an intern at a company for a little over a month and I have made a mistake. For context, this same mistake was once made by my manager when I first started and they pinned it on me, so this time around, it made it seem like I've made the same mistake again. My manager called me yelling over the phone and implicitly threatened to end my internship.
I started during COVID, so I didn't get the usual training and being in the same office as the manager, which made learning more difficult. I have started crying every day because of stress and the fear of making another mistake. This stress and fear have taken a toll on my health, but I need this internship for my school and I can't terminate the contract.
What should I do? How do I make up for it so that my manager isn't as harsh on me?
