Why do my coworkers insist on bringing me into their drama?

My coworkers constantly talk trash about each other to me. It’s getting extremely exhausting. I normally like to keep to myself, but it seems that people insist on putting me in the middle of their drama. What do I do?

I started my new job 4 months ago, I love it! It’s super easy, I work alone for the most part, and my schedule perfectly aligns with my spouses. I work mid shift, so I interact with both day and night shift. The day shift coworkers HATE my night shift coworker. They constantly complain about her to me, going as far as asking me to talk to my night shift colleague about her performance. I refused to do so until my manager (who quit recently) actually asked me to talk to the night shift employee. So, I did, delicately. The night shift employee came in early a few days later and totally went off on dayshift for the things that they’re saying. And because she went off about something that came from me, I’m now the “bad guy.” Even though dayshift asked me to talk to her in the first place. It’s all so confusing and I don’t know how to get out of the middle of it.

I’m not good at social interactions because I have anxiety and panic attacks. People feel comfortable talking to me because I validate their feelings, but it puts me in the middle of a lot of drama. I don’t know what to do or how to go about the situation. Any insight?

PS: Yes, management at my job is horrid. But what’s done is done. I just want the drama to stop.
