It will be okay.
Recently, I got a cute, but plain black laptop bag. After spending 2 years with a very ugly laptop bag, I felt so happy! The problem was, I lost its strap. My mom and I had an argument about who lost it (it was me). I regretted losing it, I kept relaying in my head how I wished I took more care but then I realized that I can make it cuter. I then got a woven strap with colorful patterns on it. My laptop bag looks even better.
In the book "The Midnight Library", the main character experiences immense regret because her life turned out to be not so great due to her bad choices. She regretted a lot of decisions. Most of all, she regretted breaking up with her fiancé due to her father's death. She is taken to a library where she relives every bad decision she made and corrects it, but to her dismay, it turns out that her life would be even worse if she did not do those mistakes. Sometimes I feel like that's too optimistic but I honestly feel like that's all of us.
It will be okay. Everything that happens is always for the best. It's too optimistic, but I will believe in this idea.
