Something feels unfair

It wasn't fair, and saying that out loud doesn't make you bitter. It makes you honest. When you've done the right thing and still got the short end, the anger that follows is completely reasonable. You're not asking for too much by wanting fairness; that is a basic, decent thing to want. Your sense that this was wrong is not a flaw to fix; it's your integrity, still intact.

Most people have known the sting of unfairness, of doing the right thing and still coming up short, of watching something unjust happen to them or to someone they care about. That sting is not small-mindedness. It is a healthy sense of justice, and it is one of the most human qualities there is. Wanting things to be fair is not asking for the world; it is asking for a world that treats people decently, and that is a reasonable thing to want.

Your anger about what was unfair is not something to be ashamed of. It is proof that you believe people should be treated with kindness and that limits should be respected. Hold onto that. The world needs more people who notice when something is wrong, not fewer. For now, let the anger be felt without letting it burn you down from the inside. It is telling you something true about the world, and about the values you carry. You are not bitter for noticing. You are decent, and that is worth keeping.
