Hey, really sorry you feel that way!! Like others have said, this is natural because you care. It's also natural because our brains are hard-wired to scan for threats and at the moment many of our brains react to law firm emails the same way we'd react to being chased by a bear. What I've found to work quite well after lots of coaching and counselling, is to acknowledge when these thoughts come up and speak to yourself like you'd talk to a child have a meltdown: "it's fine, I checked my email 5 mins ago, I don't need to do this again. The result is out of our hands, but we'll be fine in any case. Shall we go for a walk and a sweet treat?". Don't beat yourself up for these thoughts, but also remember they're not rational, they're not "real".
Plus, if it's any consolation, as someone a few years out of uni I can confidently say that where you get rejected by one place another door will open. I didn't expect to be in my current role, and it was the result of many, many rejections, but I currently work at the biggest US bank. Just trust it will all be fine!
