Sometimes there comes a time when it's hard to know who you are. It's like a swarm of bees inside, but really thoughts, thinking about what you could have done or achieved if you had done some action in the past differently. But the worst thing about these thoughts is that they make you regret. I think you can't regret the past, it's already gone and you can't change it, you have to learn from it and move on. You will achieve all your goals, you will solve all your problems, just be strong and don't let time break you.
