Camila Cabello - Crying In The Club Lyrics Meaning

I personally think this song is about a group of people that go to the same club. They all have had a bad thing happen to them recently (for example, the first one being a breakup). They don't know that they aren't the only one in pain right now. But together, in the club, they find friendship and they, just for a little bit of time, forget about all that is going on. The music saves them. They feel better. And she's saying that we all have our "club". Not literally, but a place (literally or metaphorically) where they feel better. She is saying that in our "club" there is no tears. In short: the song is saying that life is too short for just wasting it in sadness, go to our happy place.
