How can I deal with someone that is acting like a 'diva'?

If at all possible it is best to ignore those around you that act in a way you might not agree with. I have often found that the people who are the most difficult for me to get along with are those struggling the most. Be compassionate and kind but ultimately it is best to keep out of situations where it is negatively affecting you.

Be patient and helpful. Take a deep breath. Answer promptly without reserve. Be kind. Follow the golden rule, which is to treat them as you would want to be treated. No judgements but complete politeness. Do not act like you know it all but just be a great listener. Listen to every emotion that they portray in their writing. No matter the person, no matter how they act, they should always be treated fairly, compassionately, and respectfully. It'll be difficult but you should never mention the person is acting like a diva, it will anger them and you will get into an argument.

It really depends whether this "diva" is a close friend of yours or not, but if they're someone really close (enough to make an impact in your daily life) I would suggest to be very wary of everything that comes out of their mouth and filter the wrong from the right. Divas always have that holier-than-thou vibe which irks some people- and they always think they're right (no matter the action) and they always try to make everyone else follow them like their minions or followers or something. One weakness of divas though, is that they can't handle resistance. So when you become aware of what they're saying wrong versus the right, you have to learn to walk away or say no. They'll be surprised that not everyone "agrees" with their ways.

If I think of myself in that situation, I think that the most important thing for me would be to figure out what does it mean for me that someone is acting like a 'diva'. Does it bother me? And why? What are divas like? What's it about them that I don't like? What makes me think about? What am I feeling? Do they remind me of someone I met in the past? Am I reacting to them or to the person of my past? Is there something about them that reminds me of myself? Of some part of myself that I don't like? Something that I tried so hard to change, that gave me so many problem, and then this person comes and just acts like a diva like it's no big deal. Why is it a big deal for me? That's what I would think about.

I usually tell the person what I am feeling and let them know that it doesn't come off as well. I try to say it in a kind way.

if your looking to fit in with their crowd then you have to go along with it. If you don't like it and want to not deal with it, stay away from them

Give them the 'pity' look! Just kidding, but if it really bothers you, just avoid interacting with them.

Simply ignore them. They are not worth your time. Giving them your time is pointless because you can not change someone who doesn't want to change.

When I have had to deal with people like this, I've usually found that the best thing to do is to gently tell them that they're overreacting or being rude.

Sometimes the best you can do is ignore them if it's a coworker, classmate, etc. If it's someone you know then, maybe you should talk to them about it. If they refuse to listen to you, then may be it's best to cut them out of your life.
