Before you react (crying), you need to process what was said.

How about not processing for several days what people tell you?

This doesn't apply to your job, things that you usually do and what you might be asked to do, some activities are familiar to you, you know which activities and what to expect on average, right?

You go like:
-Hi CDC.
-Hi LFD.
-How's going?
-Fine, thanks.
-See ya later.
-Bye-bye.

Simplicity until you are calm enough to start engaging in more complicated interactions again.
