Okay so something happened at work and I feel sick to my stomach about it. Okay so I have a very relaxed work place and everyone is always fucking around but we get our work done. My back was really hurting so a coworker told me to lay on the ground and do certain exercises to stretch my back out. We did them and I though everything was fine until the next day when my coworker mentioned not to joke around with one of the guys because he was in a bad mood. I asked why and she said he was upset about us stretching on the ground. I felt super sick immediately. I ignored how I felt and tried to push it from my mind. Its been a few days now but I made a joke about a higher up fighting the guy who was upset because he messed something up for him. It was brought back up when the guy said "No I wont fight him unless you lay on the floor again" and I was confused so I asked him about it and he said he yelled at him for it. He said it light heartedly and never seemed to hold a grudge against me for it in the days following when it happened but I cant help but feel like everyone is upset with me because of how he reacted. I have a week left working here so I'm just going to  lay low and not do anything that could get anybody in trouble but I really just need to write this out or else I'm going to cry at work right now.
