Soldier on, keep your heart close to the ground.
Bear with it. Everything happens for a reason. Sometimes certain events are a bit inexplainable, but that's the beauty of life. You never know what life will hand you. No matter the hardships or successes, it really isn't about what happened because you can't change that. It already happened -- it's in the past and out of your control. What really matters is how you handle such situations: your maturity, poise and grace in accepting the task at hand.
