Stoicism: banal, false, or not philosophy. To be honest I used to be a stoic. And I can say it isn't even therapeutic from my personal experience. All it does is conceals emotions you're feeling without having an outlet to it. And just like a bubble, your emotions will burst. I truly think if something bothers you, address it head on. Life's too short to dodge negative things around you. Either embrace it or fight it.
I think the one part where stoicism has it right, is specifically Marcus Aurelius when he talks about how you can't control people and things around you, but only yourself. You can influence people but you cannot control them and that's key in my opinion.
