Life is too short to be always angry. That's no fun. Learn to go with the flow. Not everything will happen the way it should be, or the way you want it to be. That's life.
Change the things you do not like and accept the things you cannot change. Or, change your perspective. When you change the way you look at things, the things you look at change.
You are young. The road ahead is long. You have a long way to go. Be kind to yourself.
Cheers! 😊
