Most of the people I know who do this work do have some sort of major trauma(s) that they've had to overcome. I think it comes with the territory, in that we have more compassion and better understanding for others when we have been through the gauntlet ourselves.

Whenever you get down, just ask your guides to help you see things differently, through the eyes of love. Know that your negative viewpoint is not the truth, and that it WILL pass.
There's an article I recently read that's helped me put a lot of things in perspective. Maybe it will strike a chord in you:
