The sheepdog is anxiety, fear, panic, sadness, etc. We're the sheep. Sometimes when we go astray, the sheepdog will come after us, nipping at us and scaring us. We try to get away, but the sheepdog redirects us back in the direction of the herd and the Shepherd. When we spot the Shepherd, we run towards him for safety and in order to get away from that sheepdog.
However, once we're back close we realize that the sheepdog was simply leading us back to safety, to our Shepherd. We can then look at the sheepdog as our friend because it's only purpose is to lead us to the Shepherd and keep us in communion with Him.
(This story came from my counselor who was referring to a book by George MacDonald.)
Don't run away from those feelings. Let them lead you back to safety. Let them be there, knowing there's no danger; only an opportunity to get closer to your Maker. It's OK; we're safe. Trust in Truth!
