How do I stop crying?

I have the IUD so I usually don’t have a period but every now and then I do and it’s like it’s 4 months worth of symptoms at once. Lately, I’ve been so sobby. I’ll cry at the drop of a hat, which is really unusual. I even took off work because I don’t think I can deal with the pressure and if I cry and someone else sees me, I’ll probably just die of embarrassment.

I can’t avoid work and life forever, so what can I do to stop crying? Or at least control it until I can get to a bathroom or something to let it out privately?
