Cynicism is horrible. It is slowly training your brain to always assume the worst in everything and everyone, and has little to do with expectations. Cynicism legitimizes the anger you already feel, and makes it “okay” to yell about it, rather than taking control of your emotions.

You need a philosophy that allows you to take control, not one that justifies your helplessness. Mindfulness practices, and/or existentialist thought eventually leading to positive nihilism can help you.
