What are some ways to express a bad mood or upset?

1. If you get used to being disappointed, everything will feel insignificant.

2. No one will care about how much effort you have put in, whether you are tired or not, or whether it hurts from the fall. They will only look at where you stand in the end, and then envy or despise you.

3. The deepest loneliness is not to be alone for a long time, but to have no expectations in the heart.

4. In a person's life, there are some unspeakable secrets, irreparable regrets, unreachable dreams, and unforgettable love.

5. You will not understand the feeling of being so lonely that your throat is full of loneliness. You want to cry but you are afraid that no one will comfort you. You swallow your tears and continue to smile.

6. Some things will make you cry with tears in your eyes; some things will make you cry in your heart; some things will make you cry with your whole soul.
