A passage describing disappointment?

1. I know there is no result, but I still don't give up after hitting the south wall. I comforted myself that "I just paid for not leaving regrets for myself", but my heart became more and more sad. I have worked hard for so long and paid so much. Why didn't you get anything in the end?

2. Love often makes people full of hope but completely disappointed, but sometimes, isn't it the same with family ties? As long as you love someone, there are hopes and fantasies, and it is inevitable that there will be disappointment and pain. Bitterness is accompanied by joy, and how deep love is, how bitter it is.

I thought my efforts were enough, but I still can't hold your heart. I'm really tired and cold. It's time to let go.

We probably can't be irreplaceable to each other as before, and we probably can't love as hard as before until we all cry.

There is so much warmth in my life. I gave it all to you, but you left me. How can I smile at others in the future?
