Sure, here is a longer version of the short story:

David sat on the edge of his bed, his head in his hands. He felt like an old man, even though he was only 35. He was tired, both physically and emotionally. He had been working long hours at his job, and he hadn't had much time for anything else. He had neglected his friends and family, and his relationship with his wife had suffered.

One day, David's wife told him that she was leaving him. She said that she couldn't take it anymore. David was devastated. He begged her to stay, but she refused.

David blamed himself for everything that had happened. He regretted all of the time that he had wasted and all of the relationships that he had neglected. He knew that he couldn't change the past, but he wished that he could.

David tried to move on with his life, but it was difficult. He felt lost and alone. He started drinking heavily, and he stopped going to work. He spent most of his time sitting in his apartment, feeling sorry for himself.

One day, David was sitting on his bed, staring at the wall. He thought about all of the things that he regretted. He regretted not spending more time with his wife. He regretted not being there for his friends and family. He regretted wasting his life.

David started to cry. He cried for a long time. When he finally stopped crying, he felt a sense of relief. He realized that he couldn't change the past, but he could control the future. He decided that he was going to change his life.

David started by going to therapy. He talked about his regrets and his problems. He learned how to cope with his grief and his anger. He also started exercising and eating healthy.

After a few months, David started to feel better. He got a new job and he started dating again. He also reconnected with his friends and family.

David still regrets some of the things that he did in his past. But he knows that he can't change the past. He can only focus on the future and try to make the best of it.

David's story is a reminder that it's never too late to change your life. If you're regretting something that you did in the past, don't give up hope. You can always start over.
