Anxious night

Am feeling pretty bad this morning. Had a very strange night. Usually I don't have trouble sleeping at all (often 10 hours a night) but last night was tossing and turning and just laying there. Trying not to toss and turn too much so as not to wake David. 

Of course those times at night can be some of the worst times. Thoughts started going through my head and then I start feeling anxiety. Then I can't get to sleep because the anxiety makes me on edge.

I'm not sure what I'm feeling scared about this time, but I've not had a lot of sleep and remain feeling very anxious. It's not a good feeling at all.
