Hey any help anyone can provide is greatly appreciated...

I bought a home about 6 months ago...
In just making ends meet I owe two months on my mortgage and so I've put house on market to sell because I don't want to get deeper into debt... I need to sell within 4 months and I don't want to mess up my credit but no matter how hard I try I can't pay it all! Any advice or ideas?? Thanks so much!
