2 months ago, I had a bad record of fighting with my colleagues and it really put a damper on my work. I was really stressed out all the time and it made me lash out. I know I need to fix this but I don't know-how.
The first step is to try and talk to your colleagues about what happened and see if you can come to an understanding. If that doesn't work, then you can try speaking to a supervisor or manager about the situation. If all else fails, then you may need to look for a new job.
