There is one idea that can help you for the rest of your life. It is this: use your energy on what you can change, instead of spending it on what you cannot change.
You cannot control a friend's mood, a family member's way of thinking, or tomorrow's weather. Things that already happened cannot be made into things that never happened. Even if you keep wishing someone would change, they may not change right away, and the past will not change.
That is why it helps to ask, "What can I do now?" Instead of trying to move another person or the past, look for the part you can move yourself. That makes it easier to take the next step.
Choose where to use your energy
If you spend too much energy on things you cannot change, your heart gets tired. If you keep thinking, "Why won't this change?" you may lose the energy to move forward.
But when you use your energy on things you can change, even a small action can move something. You can change one way of speaking. You can take notes. You can prepare earlier. You can ask someone. You can rest a little and try again. These small actions are things you can choose.
For example, if a friend does not reply, thinking "Why won't they answer?" for a long time can make you tired. But you can say, "It would help me if you could reply by this time."
You cannot control another person, but you can choose your words and your next action. If you are really troubled, talking to a teacher, family member, or trusted adult is also a step you can choose.
Choose one thing that bothers you and write down one thing you can change.
