What should I do if I end up crying, and I find myself struggling to breathe?

Wash your face with cold water, or even better take a shower if it's possible. Take deep breaths. Listen to calm music.

You should try your best to stay calm and take deep breaths in and out, sit and convince yourself that everything will be okay.

Talk yourself down in your head. Like, "It's ok...calm down." do meditative breathing excercises. 1...2....3...4...5..

Take a minute to calm yourself down. This feeling won't last forever even though its feels that way. Count to 10 and inhale. Count to 10 and exhale.

Take a minute or a few seconds to calm down and breathe, try not to panic and just focus on your breath, also look at your surroundings and describe them in your head.

First, I would suggest that you take a deep breath. Focus on your surroundings, whether that's the cold floor touching your feet, the warm water running through your fingers; whatever it is. Breathe deeply and slowly through your nose and out your mouth. Those are grounding techniques that I've learned over the years

You could try doing the "in 5 out 7" breathing technique. You breathe in through your nose slowly and consistently for 5 seconds and out through your mouth slowly and consistently for 7 seconds. You can also tap along each second with your finger if it helps you.

Make sure that you ask yourself who caused you so much pain and make sure that what your dealing with does not define you

I know it could be hard to be in such a situation. But you should learn to relax and feel calm in such situations. You should remain mindful . If you cant initially just try to do. Whenever you are in such a situation try to relax as much as you can. S lowly this will become your habit and you dont have to struggle then. And yeah most imortantly you should consult a proffesional for assurance because breathing problem could be due to some physical reasons too.

Take a few big deep breaths and concentrate only on them.
