Where is the sleep?

I should have taken a sleeping pill hours ago, but I wanted to see my son when he got home from his band comp. they placed 2nd overall. I'm very proud of him.

Now my brain will not shut off. I just can't stop thinking. I've been completely depressed over the past few days and I keep running through the few days leading up to both of my waters braking trying to figure out what went so wrong. Maybe I was too stressed out. Maybe I should have been on bed rest with the girls from the start. I mean I had problems carrying one baby. What made me think I could carry two and just go about my normal activities. 

I wish my brain would shut off long enough for me to go to sleep for a few hours.
