Save my house

So, I've never been one to ask people for money, but I'm in a tight spot now. My ex-wife has been out of my house since March of 2017, and we've been divorced since April of 2018. As part of the divorce settlement I got the house and the kids but no child support. I have been supporting my 2 teenage girls on just my income for almost 3 years now. Medical bills, food, insurance, etc. has depleted my funds and as a result my mortgage has fallen behind to the degree that if I don't come up with the money they need my house will be foreclosed on and sold on January 7th. I need $7,500 to stop the foreclosure and I need it by December 30th. Any help will be appreciated more than you will ever know. Please feel free to message me with any questions you mighthave. Thank you for reading.
