In times of grief you learn some things. Here are the things I have learned:
1) your life is not over because you have a bad day. And a bad day doesn't mean a bad life.
2) family may be all you have, but do not take them for granted because one day you'll wake up and they'll just be gone.
3) God has a plan. He has everything set out for you and even though you can't see it in this moment, everything is going to be okay.
#3 is by far my favorite.
