Emotional Roller Coaster

I cried myself to sleep last night, but finally slept. I woke up around 4am to go to the bathroom and found DH sitting next to the bed, just watching me. He had been up all night long, "watching to make sure you were alright", as he explained it. Today, he was edgy. In fact, he was worse than a pregnant woman waiting for labor with an overactive nesting instinct. I'm worried about him.
