It's a tense environment given the current COVID situation in general. Maybe people are tense given that layoffs are occurring within so many companies, and perhaps your co-workers are concerned about their own jobs and job security. People may also be tense over COVID itself, and the many issues that presents.

Try not to take it so personally, if you can. I know that's hard, but people react in different ways when stressed, and if you're picking up on a vibe of tension, I am sure individual and collective stress is contributing.

Just be yourself and do what naturally comes to you. That's all you can do.
