I'm sorry. I know there isn't a whole lot I can say at the moment to make these feelings subside.
There is a plan and it is better. I admire your faith. All we can do is walk the path. Your faith and beliefs will get you through this. Who knows maybe it had to come to this for her to wake up.
I know exactly how you feel when you say it's so unnecessary. That is whats most difficult to understand I think. Never lose that faith of yours, all things are possible. You will come through this much stronger.
