Is this an example of trying to downput someone? Does it mean low self-esteem?

A friend is very popular in a certain nightclub, has been for ages, and hasn’t been there for about five months.

Now her best friend who is light-years behind her in terms of mind health (I’m more than sure) went out as usual and when reporting the night said that “nobody is asking about you anymore”.

The best friend is prone to jealousy and throwing tantrums.

Without me saying more, what do you feel about this?
