The night I got my dog was the night I stopped crying myself to sleep. The night that the uncontrollable flashbacks calmed down, and that I got a full night sleep.
He is a little dog, only 8 lbs, but with him next to me I feel somehow protected and safe, I have an extra pair of ears so I can be a bit less on guard all of the time. I'm just amazed at how much was relieved once I got my dog :)
