Guest, I am 63, and I understand how you are feeling, and often share it. I found one answer, which is a bit selfish, is to narrow your perspective down to the things that you can affect personally. In other words, make a difference in the places you can, and let the larger picture resolve itself. Help with the larger picture if and when you can, but definitely do what you can in your own sphere.

Of course America wasn't supposed to be like this. Nor was the world. What went wrong? There are too many answers, and the problem is too complex to sort out. If you make yourself depressed and nonfunctional, you will simply have worsened the problem -- draw your vision in a little and do what you can.

Hope it helps.
