Is it me or 👀

So one of my coworkers and I usually go on walks at work in our building. But I noticed when one of our other coworkers are in the office they go together without me. So, my anxiety is telling me a couple things:

1) they’re talking about me

2) to watch out for her

Am I overthinking this??? The other coworker she walks with really doesn’t say much to me at all..
