Angry at someone or about something?
Solution?
Go do something for someone. Go make some cookies, help clean someone's room, tell somebody something you appreciate about them, even if you may not like them. Are we not all human beings, created in the image of God our Father? Are we not all brothers and sisters? Even if you do not believe this, it is common human goodness to treat others with kindness. We make the world a better place by serving each other.
So, are you angry about something or are you angry at someone? Go do something for them. Do not harbor anger or hurt in your heart. It will become a poison that slowly eats at your human decency and your very soul. You must get it out in positive ways. It will work, I can promise you. When I was put out with missionary companions while I was serving as a full-time missionary in Alabama, I did something for them. Even if they were still mad at me or were meant to me, it did not matter. I was doing something for them and helping them have a better day. The circle of good deeds is real and true, but it cannot go forward unless you pay it forward and do something for someone else and DO NOT EXPECT SOMETHING IN RETURN. Do it out of your own heart. Give a good gift in humility and peace. Go try it some time. You may find perhaps that he who was once your enemy may become your friend. And it's always good to have more friends.
