Anyone else have the baby blues last longer then ten days?

All the online info says the baby blues disapear by day 10. I am still having mood swings through out the day and Im on day 11. Should i get to the doctor straight away? or is it normal for it to take a little longer then ten days for some women? This is my second child so it is a little over whelming with a toddler who just gave up naps and a new baby and my blues show themselves mainly as stress. I get really over whelmed sometimes and have a few break downs and feel quite anxious when the baby wont sleep or my toddler acts up.
