It could take years before the reason is clear

I truly believe that everything happens for a reason. One day you will look back and the reason it happened will be suddenly clear because you realize had it not happened you wouldn't be where you are today. It can sometimes be so difficult when you are going through it that you can't see any positive reason why  it could be happening. The reason sometimes is to help someone else get where they need to be. But most of the time it is exactly what had to happen to get you where you need to be. It may feel like a tornado just came into your life and destroyed everything but whether you will admit it or not you were never going to get there so it took a tornado to move you there. Just hold on tight and see where you land when it's over. Then you can get up and put your feet firmly on the ground and grow wherever you are planted.
