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

Take very deep breathes. When you take one your stomach should go out. Hold the breathe for ten seconds then let it out. Do this repeatedly. Also works for panic attacks.

A brown paper bag sounds cliche, but there's a reason. It helps to focus on just your breathing. It will also calm you because since you'll be breathing in mostly your own discarded carbon dioxide, there will be less oxygen, and it will help to slow you down.

I should stop crying for a while and ask myself that what is the actual reason for I m crying and will it be useful or will it give me the solution? If not then why would we do so.

Go get some fresh air and cry it out. Letting go of all those emotions is best and you'll feel better to move on.

Try finding a quiet spot. Once you are comfortable with your location start concentrating on your breathing. Count as you breath in, count as you breath out. Try to work on clearing your mind while you breath. You can confide in someone if that is an option. If you can remove yourself from the area that is upsetting you.

I would say that the best thing to do if you can is to go outside and take a break. Another thing you could do is find someone you feel like you can vent to, you could also try to not think about anything to try and calm yourself down. There is not just one way to do this.

look around you. find 5 things you can see, 4 things you can touch, 3 things you can hear, 2 things you can smell and 1 thing you can taste.

There is nothing wrong with crying and if you struggle with breathe, try to calm down and breathe deeply through your nose than exhale through your mouth.

Ohhhh, I know this problem well, the gasping, the croaking for breath, panicking that you will never be able to take that next breath, but there is a way through this. Remember that it is ok to cry, it is ok to really scream with rage or sorrow, we are all human and this is out way of getting through and crying is one of the best releases for pent up human emotion there is but when we cry we heave out breath and forget we then need to gulp in air and breathe. Slowly try and breathe in through the nose and also out through the nose too, the controlled channel of air means that you need to concentrate for a second and that slowly breaks the cycle. You Can Do It! slowly. . .

The key thing to do in this situation is to work on controlling your breathing. You will want to count your breaths and focus on taking deep, slow breaths.
