I wish I could give you an answer that would cure you of your frustrations. Unfortunately, there is not a cure-all answer for this.
Coming from a biblical perspective, I believe that each person goes through trials to help them grow. It is our choice. We can either allow these problems to make us bitter and afraid, or we can use these problems to educate others and help ourselves grow.
Can you fix what is going on with your parents? No.
Can you make others in your country treat people with respect? Not all of them.
What you can do is be the voice of reason, educating people on the goodness of being kind. You can choose to find joy even when it's not obviously present. Look for the good in life and choose joy. Try to be a light for others, who feel they are trapped in darkness, even when you feel you too are in that darkness.
We cannot change others, but we can change ourselves.
