Buying a home?

I am so stressed over buying a home I dont know what to do? I have only been doing it for a couple of months but the past few weeks I have been getting nothing but migraines from this off again on again process. The Brokerage company only seems to be dealing with this one bank and they are so lazy with debating my wants and needs. I know that I am nothing but a number and a new pair of shoes for most of these people but there has to be a better way than this. I have given them every piece of information except my DNA and they still dont seem to be satified, I have been trying to close for over a month and they say one thing but draw a contract for another, please help; what should I do?
