Gratitude as it's frequently been explained to me just sounds like slave-mentality shaming. There's a strong distinction between it and recognizing and accepting what you can and can't change. Genuine gratefulness isn't a bad thing in and of itself. It's not a forced emotion. Gratefulness as a mantra in practice is just guilt tripping, it informs you to feel shame for negative emotions. It's a healthy response to be upset at some circumstances. Being grateful for being dealt a bad hand is for the birds. Someone might chime in to suggest that's not what gratefulness is about - I'll save you some time, I disagree.
