my app keeps getting pushed back

And it's is getting annoying a frustrating. Yes I u derstand why women who are in labor come in and they take priority Sure but it gets under my skin when first I'm told 5am then the night before I'm called and told 6:30 and at 5:20am I'm told they will call me between 7-8am with a time because some women came in. I already haven't slept well because of the excitement and now I am tired but can't sleep! Grrrrrr so frustrating!
