Even the worst nightmare has an end, and if it still does not endning, need to try to wake up, or he will destroy us.
But the scars recieved in it, will remain. Maybe life will not be good as before it. It is unknown, will all that good feelings, friends, love, that was lost because of it, will returns someday. At least, some good memories about whate was lost, will stay forever. And the most worst has already passed, and it's possible to leave what was before, and moving on.
