Interactions between colleagues of lower employment status.

Was working late at work and overheard two other people having a conversation. They knew I was in the next room and hey were in the corridor with the door open. The girl started to ask the guy what they thought of a particular girl at work. They were commenting about how a person works and the guy kept saying 'she thinks she knows everything! She thinks she knows everything!' I thought they were speaking about me as they referred to something like someone who smiles when in the middle of a particular job (interacting with people), that he had seen what I write, and he would expect more/better from this 'girl' at this point. The girl made some comment re this person being a boss in the future. What would 'she' be like? They laughed.

I had already felt nervous since this girl/guy's manager were with them earlier and he took her aside and talked with her in a separate room. I have no reason to think that he was talking about me but yes, I do feel insecure in my work as I've not felt confident in my work exams.

In contrast, my bosses have regularly given me accolades, told me that I'm good at my work and think I'm sensible. They are also trust me to work with little surveillance. This is something I've noted even up to the moment I heard the guy/girl having that conversation. They would not be colleagues of mine in the same profession. They would be working in allegiance with me.

Am I just allowing my insecurity get the better of me rather than the reality?
