Easily irritated not sure if its fed up or hormones

I'm feeling very not short worded and over people today. I had a nice vacation and had to go back to my work. The people there always gossiping and are just negative af. I dont entertain it most of the time and try to avoid talking to these people as much as I can. I mean what adults sit in the same room and text talking shit abt people. 😤😤
