If you're about to cry in a situation where you really don't want to cry, immediately start doing difficult math problems in your head at a rapidfire pace. As soon as you solve one, jump into a new one and keep going until you notice the physical cues for crying have subsided, then for the love of all that is holy, avoid direct thoughts of whatever made you emotional to begin with lol
The key is the math problems need to be difficult enough that you have to stop and follow the operational steps in your head, but also still solvable for you personally. If they're too easy, your brain will give the answer without switching emotional/cognitive gears. If it's too hard, your brain will disregard the question & keep you in the emotional place.
This has been very effective for me when I needed to hold it together for just a little longer. Just be sure to circle back and feel those feels fully when it's safe to do-so so you can actually work through them. It's detrimental to your mental & physical health to constantly push them away, so...don't do that.
