I do hear what you are saying, and I agree in many ways. The truth is, even tomorrow is not a certainty.
I am not one of those "glass full" positive kind of hopeful people. However, I really like that saying about living today like it was your last day on Earth. I think we all might be happier if we could do this. Obviously , it might not be possible to do everything you would actually do.. but hey- try a few things you CAN do.
Tell someone you love them, take a hot bath, buy something you like. Do something nice for someone else..Forgive yourself just for today. Then get up tomorrow, and repeat
And most importantly....
TURN OFF THE NEWS!!!! Seriously!!! And delete all of your news bookmarks! If something happens that you REALLY need to know.. it will come and find you!!
