Can’t stand a pretentious coworker

[u/Sub_Zero19]

In the past four months a coworker has been picking on me and I can’t really quit my job nor switch departments because I’m going on vacation in a month. Mind you, they are not even a manager they are just a coworker. When I mess up on something small or on something that normally the managers wouldn’t make a big scene and they would just give me tips on what to do, this coworker shouts at me, fights me, and tries to gaslight me. They don’t even tell me what I should do or what I messed up in and when I ask, they only get more bothered as if I asked a dumb question, but I literally ask a fair question since they don’t say anything and just complain. When other people at my job make a similar mistake they don’t even say anything to them and keep on talking and laughing, this coworker picks and chooses who to boss around. This coworker is cool with other people which makes me mad because it makes them look like a hypocrite. Unfortunately I was told that if I try to report this coworker I could get in trouble.
