There's no need to overly empathize with many things and many people. That's not your responsibility. Just say, in the future, take better care of yourself. And don't waste yourself on things that have nothing to do with you.
Many things have happened, from the perspective of others, it's just a topic for discussion, but for yourself, those are your experiences. Some are sad, but you have to learn to be strong and face what has happened calmly. At the same time, learn to comfort yourself. Many things are beyond your control. Once they happen, they will happen.
From now on, you won't be afraid anymore. It's okay. Hug you. Everything will be over. By the way, it's almost the break time. Then I'll accompany you to bask in the sun and ride your favorite bicycle.
