Susan,
When my child was born I, too stressed over everything. Like you, i was unable to controll my thoughts (which I usually could do). They would always go to "the worst case scenerio". Over time it did ease up and I heard from other moms they many of them went through it. Time alone, walks and a lot of deep breathing helped. What I found out later was there is Postpartum stres/anxiety disorder. I had only heard of depression, and I wasn't depressed so I never looked into it. Look into it and talk to you therapist about it. Short term meds may help along with relatxation tools. It will get better, but help along the way is a good thing.
