Greetings friend @franyeligonzalez.
It is very true what you express, some people make us lose our sanity in certain occasions because of not controlling our emotions, but, it will always be necessary that we control ourselves, it is important to highlight what you say:

One of the keys that we can apply to face a difficult or toxic person is to take a deep breath and not respond in the same way.

It is an important recommendation since it is the key to face uncomfortable situations and in this way not to fall into the temptation to act in the same way as certain toxic people do.

As usual my friend I enjoyed reading your article, thank you for sharing it. Best wishes.
