Is it normal that I feel 'delays' in emotions; or feel emotions extremely all the time but can't express or communicate them?

Does this make me come off as an alien to others especially if they notice any of this stuff about me?

I remember recently a coworker said soemthing so mean about me to my face and someone else tried to hype him up I think it’s cause they wanted a reaction. And the coworker was like “are you mad at me” and I said “no” with no emotion. I actually was just thinking about what he said to insult my appearance and shrugged my shoulders internally.

then like an hour later I started thinking about it again and I got negative feelings about what he said. The more I thought about it. But I went totally quiet on him and then like a few days later or whenever I saw him at work again I was totally silent when he tries to talk to me. Because I don’t express my emotions for some reason. I also just decided to cut him off.
