Help me save my home

Please help me reach one step further having a roof, a home for my family,after several years I am now in the process of becoming a first time house owner, I got the opportunity to finally purchase the said house that my family and I are living in presently . We worked honestly and hard to saved and got the down payment and so far have covered all other document cost etc but due to covid 19 things have changed drastically where our income was no more as now my family and I are looking to raise money to get the closing and legal fees for the mortgage and am being told if don't have the fees the vendor can still put up the house for sale and my family and I may end up in the streets and lose our down payment .We are out of savings and have no where to turn .We just can't seem to find this money any where and after reaching so far and all the sacrifice I don't want to lose my down payment or become homeless or the opportunity to have a house for my family. Also in this pandemic it has made it more difficult for me to do any other means of getting extra cash. I have never done this kind of thing but really desperate and asking that anyone out there who can help or or contribute a little to donate to this cause out of the goodness of their hearts. May God continue to bless you and your family and keep you all safe and healthy in this Covid 19 pandemic.
