no sleep

I feel awful. I worked late last night and work was so stressful, I was dreading being back up at 5:00am to do inventory and counting the hours I would sleep. I think the baby felt my tension and unease because She gets up and wouldn't go back to sleep for anything and was inconsolable, I was pacing frustrated and hit my dresser with my hand stupidly and not only hurt my hand but I think she heard me and sense my being upset and hurt her feelings so I held her and she fell back asleep but I feel like the worst mom in the world for letting her see me frustrated!
