Lost Mother and Now Losing Home and need Help

My name is Justin and My Mother passed away Oct 2 after being in the hospital sense May. We thought she was going to pull through but in the end she got worse very fast and it was heart breaking. the last time I spoke to her I promise I would take care of our house. Ive done everything I can but the sad truth is I dont have enough to keep the house and pay the property taxes unless I have a mircle. Sadly a trusted family member took alot of money from me and that money was to take care of alot of rent and property taxes and now I have lost all of it because of them. I don't like begging but I fear I have no option and me and my girlfriend are trying to make ends meet but with the money taken its pretty much end game. Anyone nice enough to help us during this horrible time would be a very big thank you
