How do I calm myself when I feel like I'm about to faint or I'm overtaken by all the emotions inside me?

I personally either do a quick "Yoga with Adriene" flow video (on YouTube. She's amazing), or do any video that teaches lion's breath.

Personally, I believe that a great approach to calm myself when emotions overtake me is to view things in a different perspective. There is more to life than the emotions I feel. If I view these emotions negative, in an instance. They will affect me negatively. If I view these emotions positively/ constructively and turn these emotions into something that will help me become emotionally stronger in the future. I can avoid being overtaken by these emotions.

I am thinking about my majestic future after then I become calmer. Also i am trying to avoid from problems in my head.

To calm yourself when you feel like you are about to faint or that the emotions are overtaking you, I would recommend taking some deep breaths and even going into a nice, quiet area, if possible. I know how it feels when your emotions are taking over you.

Always good to give yourself some space and time to deal. Move away from the crowd and get to a private place to deal 1st before joining the crowd again.

Don't forget to breathe. Focus on that if you have to. From there, I like to find something to distract myself with. My favorite childhood movie, or a good TV show. Sometimes even some relaxing, positive music helps. Or maybe you like drawing or writing or reading. Find something that calms you down and makes you happy.

Just remember to take deep breaths and go to a quiet spot. If all else fails you can always speak to a close friend or relative about what's going on.

It is good firstly to notice those moments, what exactly happens in these moments. Then except these all emotions and not judge yourself or feel bad about it. Except them as joy, surprise that they are just emotions nothing bad about the. Then if it is possible sitting down and deep breathing - counting till 6 inhale pause for 4 seconds than exhale counting till 8 and pausing again. So, is good to do some for minutes. Than if there is some water you can drink a little and start rethink the whole situation, try to see the cause of this unpleasant emotions and step by step deal with them. Remember you are in control of your emotions, not they are controlling you! And you might need to consider is it anxiety and which type, read about anxiety and see where you at. There might be test in internet to see how you are doing in controlling it. It is always good to deal with anxiety because it can be hard living with it. Therapist could help you in that. I wish you all the best and hope you find solution soon!

I press the tips of my 4 fingers to my sternum or lightly press my fist against my chest and take as many deep breaths as possible to bring me back/ keep me focused. I remind myself that whatever is troubling me is only temporary.

Have a seat, take a deep breath, and drink some water if you must. If you have someone you trust with you, then tell them what you feel. Sometimes you'll feel better after telling someone how you feel. Or if you're not comfortable with sharing what you feel, just ask them to be there and comfort you.
