Down payment istance HELP! Closing soon?

Closing date is Sept 15 went to sign escrow docs and loan docs but noticed everything was off! Loan office did not disclose many things including the fact our closing cost note was going to be a different interest rate 8% AND we initally went in with everyone saying OH DONT WORRY you will get your earnest money deposit back 2 GRAND once escrow closes. YEAH RIGHT we went in there and they told us we still OWED money my realtor (supposedly) in good faith gave up part of her commision to pay it off but.. i was counting on that money we bought an REO property with whats left of the Down Payment Nehemiah prgram and the access program... we are scwed. Oh not to mention out payment went rom $1518 monthly to 1668 + 58 for Down payment istance note plus 90 dollars for hazzard insurance... I just feel lost they are pressuring us to buy saying ITS ALL GONE after Oct 1st 2008 and you wont be able to buy anything. We bought a 205K house and ended up with a 220k house after all charges.. in the long run im paying 450k after 30 years 6.75% on first note and 8 % on DPA note... i cried so hard at the escrow office because our lender never once mentioned anything and i DID ask questions now I've run out of options and our dream of owning a home is gone along with the help of DPA I still dont get how the Nehemiah program helped me if they EITHER WAY I still had to pay alot of money out of pocket... in the end If I walk away i leave empty handed without my 2 grand and no home excrow keeps whatever monies ive given.. what to do :(
