What is a word you feel that too many people use?
There are several words that many people use incorrectly or dishonestly. Not by ignorance but rather omission/manipulation.
Some people will say just about anything to make themselves appear more desirable to other people.
People need to say what they mean, mean what they say, too much hypocrisy in the world I think, and a lot of self-service.
Love
Many people say the word many people express the word, but they don’t mean it. Many are just going through the motions. This word means something important, but it’s just just an auto pilot thing for many. Bottom line don’t say it unless you mean it I always do. 
Empath
Many men and women claim to be empaths. I think this word has become quite fashionable. I don’t think people realize how difficult it is to be an empath and that most empaths if not all of them wish they weren’t. From my dating experience, I think others use it as a means to make themselves appear more attractive to potential mates.
Narcissist
This is another word that is become overly used on people. A narcissist when labeled as such by me, is someone who suffers from narcissistic personality disorder. They gaslight people they manipulate and they absolutely loathe themselves so much that they make others feel worse so that they might feel better. This is more than just a selfish person. This is the person that will happily destroy your life to make themselves feel better.
I don’t wanna get on a ranting rave here, I could list a whole bunch more, but I think a few are enough to make my point.
As always, thank you for reading…
