Another Boring Week at Work? Or Am I Just Oversensitive?

So here's the thing: it feels like my coworkers and boss have been giving me some major side-eye lately, but maybe I'm just overthinking everything. Last week was pretty uneventful, more of a run-of-the-mill office-week than anything special, but somehow every little comment or glance makes me wonder if they're planning their next move to get rid of me before the end-of-year performance reviews even come around. I didn't exactly set myself up for this, mind you. Monday started off with my usual routine: clock in a few minutes early, sip on my coffee while perusing emails, and pretend I'm not checking out all the gossip from last night's office party that somehow got leaked onto Slack. By lunchtime, I was feeling pretty good until our team meeting where my boss, Steve, mentioned he had some questions about Project Z, guess who leads Project Z? Yep, me. Afterwards, I saw Jane and Mike whispering a bit more than usual as I walked past their desks. Did they know something I didn't? Were they planning to take over my projects while I was still on the hook for them? Or maybe it's just that one of them is trying to figure out how to ask me about Project Z without coming off like they're nosy, which is totally a thing because we all know Steve's super private. I tried to shake off these thoughts during the rest of the week. Wednesday I had a meeting with clients where I got some good feedback on my presentation skills, right before Steve suggested that someone else might handle future client pitches since there were so many coming up soon and Project Z was demanding all my attention. By Friday, I was convinced they were plotting something sinister. Maybe planning to take away my title of 'Project Manager' or worse. Now I'm here on this site wondering if any of you have had a similar feeling where everything seems off but maybe it's just your imagination running wild. Am I the asshole for overthinking every little thing? Or am I really being ignored and sidelined in favor of someone else?
