I think that friendship does not exist

I'm going to be talking about how I see things, just because I make a post about it doesn't have to mean it's true it's just a few observations from my own life experience. People tend to say that they want to know the real you but if you do they'll just get sad and stressed out so I learned that I need to be cheerful and bubbly because if I'm even the slightest of moody people won't like me. Most people are friends with you because of convenience and making friends isn't even about doing it with people you like, it's being friends with the right people because if you aren't you'd be an outsider since there's cliques everywhere and cliques are triggering like I don't like seeing friend groups it makes me sad, you need to be friends with the right people so they see you cause otherwise you're invisible. Sorry I just wanted to get that out of my chest.
