My son had surgery & I'm exhausted

My son had surgery this morning - he had his adenoids removed & tubes put in his ears. Nothing really serious, but still nerve-wracking for us. I'm exhausted. We had to be at the hospital at 6:00am, and so we had to get up at 4:00am. The lack of sleep and stress of the whole thing really got to me... Just wanted to check in really quick... I'm out of here!
