Tell me a sentence about the sadness that makes your psychological defense collapse instantly.

1. Time will dilute a person's memory, but it can never make people forget those memories. 2. How many times does a heart have to be broken before it is forced to give up? How many times does a person have to wait foolishly before he realizes that he is redundant. The heart that is now frozen was once the warmest; the person who is now ruthless was once the most affectionate. 3. Some encounters between people are like meteors, which burst out with enviable sparks in an instant, but are destined to just pass by in a hurry. 4. Everything and everyone will become a thing of the past, don’t live with it. Letting go is to move forward better. 5. There is always a place or a person that makes your heart flutter and leave you nostalgic. There is always that one person whose words of apology will make your heartache and be unforgettable. 6. Only after taking the initiative for a long time did I realize that my heart had gradually cooled down with the lukewarm words; only after I cared too much did I feel that my love had slowly disintegrated with the indifferent attitude. 7. The whole city is asleep, leaving only me and my thoughts that can't sleep. The night is still young, love has passed, and you, whom I haven't seen for a long time, occupy my memories again. 8. There is no empathy in this world, so don’t stupidly open your wounds and complain to others. There are more people spreading salt in this world than doctors. 9. I wish I would get seriously ill and forget how you look when I wake up, and forget that I love you till my heart breaks. 10. Inadvertent longing is so painful, it hurts so much that I dare not touch the memory. Time cannot take away the pain, it is because people get used to the pain. 11. Some scars, scratched on the hand, will become a thing of the past after healing; some scars, scratched on the heart, will remain in the heart even if the scratch is very slight; some people are close at hand, but they will never be destined for life. 12. One day, you will calm down, look at your own story like an outsider, and shake your head with a smile! 13. Don’t be sensible too early, don’t be too involved in the world, don’t love too much, don’t sleep too late, Don’t eat too much, don’t be too nice to others, and don’t believe too much. 14. There is no first-come-first-served relationship. It was obviously me who met you first, but you gave all your tenderness and patience to the people who came after you. 15. Some people can’t tell what’s good about them, but no one can replace them. And some people can't tell what's wrong, but they can't do anything about it. 16. People who are separated from each other, no matter how familiar they were, will gradually become alienated. 17. The two luckiest things in my life are that time has finally exhausted my love for you. One thing is that one day a long time ago, I met you. 18. The biggest regret is that even the breakup cannot be explained face to face. Maybe a hug can solve the problem, but in the end we are strangers without any explanation. 19. Our love is like a shooting star that has no time to make a wish. No matter how beautiful it is, it can only be the past. 20. It is not a terrible thing if a person completely disappears from your life. The most terrible thing is that you will never be able to enter his life again, but he is still everywhere in your life.
