Miss a person's mood?

Good morning! The feeling of missing someone is that you will want to cry, laugh, grieve, be depressed and worry about that person. But at a loss, I want to find that person, but I am afraid. My heart is pounding and every day will be long. This kind of experience will make you mature, but it will also destroy you. There is a saying-how can the outside world compare with your shy smiling face? Don't indulge yourself too much.
