Life is, and will always be, a mixed bag. Even if you made decisions, you made good ones, too. Sometimes, though, you can't see all the good that's going on because the bad is blocking your way. Keep going, and the good will reveal itself ^^ Remember - if today is the worst day of your life, tomorrow will be better.

Look, we are all bound to make bad and good choices. No matter how hard we try, we're still going to make bad choices. It's part of our life. We make bad choices because we are human. We are not perfect. Because of these two elements, we're always going to make bad choices, no matter what. However, we can make good choices in exchange for the bad. We make good choices to make the bad ones go away. Mistakes do go away; they just scar and linger for a while.
Don't give up. Keep on fighting. We're all struggling with choices. We all feel like to give up. But, we continue fighting because we can better than those bad choices that we make.
