Depersonalization at work.. how can I ground myself rn

So I work at a movie theater and I was doing hall checks Yknow walking around and picking up popcorn and all of a sudden it hit me idk what but it hit me and i called my mom and started crying so now I’m in the bathroom crying because I’m currently freaking out and I’m scared to leave the stall because I’m scared I’ll freak out more idk what to do right now it’s most likely my anxiety right now but my body feels weird and im worried what was happening a few weeks ago is happening again.. can anyone help me rn ? I have to clean at theater in like 20 minutes 😂
