frustrated!!!!

Okay so we have less then 2 weeks till we HAVE to close. We have been calling the mortgage company this lady never calls me back, never returns emails. I'm so stressed out. We need to know whats going on. I don't think we are asking much. Just yes the appraiser has been ordered. Or yes things are getting started with the underwriter. I'm not giving our notice at the apartment until we have the keys in our hands. I have a feeling that people will drag their ass and not get everything done buy the 30th and they will foreclose and everything will go up in smoke. I'm so nervous and stressed. Pray for my sanity!!
