How can I calm myself when i'm surrounded by a massive crowd of people?

Use your pointer finger and thumb as a mechanism to that sends you to your happy place. So when you are in a big crowd and feeling a little over whelmed just place those two fingers together and picture yourself in your happy place. Focus on people or animals that might be with you, the smells, sounds and what is happening. Hopefully that will calm you down enough to make it through the crowd. :)

Take a moment to breathe, and just remind yourself: The reality is that even if you're experiencing chaos internally, nobody is likely to jump to that conclusion if they do happen to glance at you. Chances are they'll just think you're shy.

try and focus on someone/something thats makes you smile everyday/always like your friends don't they make you smile? :)

If you can, do a mindless task. A mindless task could be scribbling on a piece of paper or sorting stuff into categories.

calmness is our inner strength... outside chaos crowd is external get deattached an feel ur inner stablitiy

just take nice deep breaths in and then just pace yourself slowly and be calm Just remember that its fine

Close your eyes, take a deep breath, shut out all the voices around you, and just focus on your breathing or heart beat.

It's something I have been working on myself. Sometimes I have no problem being around so many people, for example I regularly go see baseball game at one of the biggest stadiums in the US. I have no problem with that, as long as I am on or close the isle. However, I've had some classes in college where there were roughly 20 students, where I simply couldn't calm down, because I felt like there was no space to breathe. Ultimately, I think it has to do with how much you feel vulnerable in these occasions. Try to see the crowd as something that is not there to judge you, comment on you or do anything to harm you at all.

By grounding yourself down you will be able to handle these situations better. Look up resources on grounding your energy for further studies on this matter.

If you can, stay calm and remove yourself from the area. If you can't take deep breaths, if it helps close your eyes, and try and find a friend and/or an area where you have a little more space.
