Sometimes we don't get to choose what happens to us, but we do get to choose how we respond to it.

Essentially, what we are doing when we focus on something being 'unfair' is externalizing the blame and blaming an external 'world' that you just don't have control over, instead of actually attempting to deal with the situation. I know it's hard. I've been in this mindset as well. But the only way to heal yourself is to focus on healing yourself.
