Honestly, it's not cynicism, although it used to be until I really thought things through. It's just the truth. I have a great life, I have truly been blessed, and I am very thankful. But to me the glass is already broken. Things may come, things may go, the only thing I control is me, and I am at peace.
Again, that's a very healthy mindset to take no matter what the human condition is, but you don't have to take a scorched-earth perspective on life to adopt such a frame of mind. And for most people, who haven't developed such a frame of mind, that scorched-earth perspective can be really destructive.
Additionally, the part about relationships goes further than simple nihilism. Plenty of relationships are real and go further than transactions. Not all of them, but many of them. Again, I don't know who hurt you to make you take such a perspective, but your perspective is deeply skewed.
Ah I'm so glad you posted this! I've been trying to articulate a rejection of cycnism so it's perfect to have the opposite case presented!
I know it is semantics but it's important. You say "it's not cynicism", "it's just the truth". Cynicism is the belief that everyone is almost entirely self-interested. It squeezes out the possibility of altruism and generosity. Its sort of irrelevant whether it's the truth. So you are cynical.
Love that you've found some joy out of being at peace with your worldview.
