It's time to re-evaluate my life

When I was in college, I spent one year living in the sorority house and 1 of my 3 roommates would decide, after about 2 months of drunken debauchery, that she should re-evaluate her life. This usually occurred after a particularly crazy night of partying that resulted in some not-so-smart decisions. You wake up in the morning, full of regret, wishing you hadn't had that last tequila shot, and thinking, if I could do this night over again, I would. And I would change everything. But you can't. You can't change anything. And you did take that last shot right before you made that poor decision. And you begin to feel that the only way to make up for this self-destructive behavior is to "re-evaluate your life".
