Weird comment from my boss has stuck with me

I work at a restaurant and have recently been training to be a server. Last week my manager pulled me aside to tell me that she can tell I’m not upbeat and bubbly and she’s not going to “ask me to change my personality” or “get mad” that I am how I am. I think she was trying to tell me that I can be a good server despite my personality but I was never worried that my personality was going to lead me to failure. I have years of restaurant experience I think if my personality was going to deter me from this job it would have already.

I keep coming back to the question that never seems to go away: am I that weird and awkward that people need to point it out all the time?????

Am I overthinking this? I feel like she was just telling me she thinks i’m weird in a backhanded way. Was she being rude to me? Or nice? Idk it really feels like totally unnecessary thing to say and it has stuck with me and is making me second guess what people think of me at work
