How can I tolerate the injustices that my country promotes?

Well, I'll try to explain it as clear as possible without making this too long.

My country's government is a disaster, not only the current head of the state but the system as a whole, it's a complete disgrace. This horrible system promotes discrimination towards specific groups of peoples under no valid reason, and here I am living the discrimination the central government of my country promotes, can you believe it? my own government is openly and legally discriminating me (me and many other people for the same reason) for something I have absolutely no control over. It's 100% unfairness that I can't change and I'll have to live with this as long as I live in this country. And the worst part is that many people (mainly the people benefiting the discrimination towards the group I belong to) openly endorse and approve this discrimination based on fallacies they believe in. Not only my own government is discriminating me but many other citizens openly do so as well.

This situation is really exhausting. Plus, it doesn't help a flaw I've had my whole life: I'm a really wratful person, not to the point of like beating a person, I've never done that in my life, in my case it's like feeling like my blood is boiling and I can say really mean words to anyone without caring about anything in that particular moment, I have always been quick to anger, I don't trust myself in this aspect becuase I know I can lose control at any time, and these injustices in my country don't really help much tbh.

I'm slowly coming back to the faith after a decade of being away from Catholicism, and despite these unfair laws discriminating me and other people, I want to learn to be less wrathful (idk if that's the right term, English isn't my first language) because I know that's what Christ would want for me.

Any advice you can give me would be of great help. Thank you very much.
