Narcissism:
Exaggerated and excessive admiration that a person feels for himself,
for his physical appearance or for his gifts or qualities.

Having this concept as a basis we can say that it is something literal.
At some point you can feel so good with yourself that in social networks you express it that way,
being direct with your beliefs, with your appearance and intelligence but sometimes you can also be in a bad mood, sad or depressed and the social network does not give you That mood you need, you only get it in real life with your loved ones. Then the social network makes you be null in that moment where without any problem you can share from your joy to your sadness. Everything is mental, if you use it only to publish your vistorias and hide in your defeats you will opt for a narcissistic stance.
