I'm going to lose my house

I was in an abusive relationship for years. I never stood a chance.  It started with two violent alcoholic parents plus the added fun of mommy being a heroin addict. I went from the rape by a relative to one abusive relationship after another.  I still managed to pull myself up by my bootstraps, went to school during the day and worked full time nights at an all night gas station.   I graduated and got a great job and bought this house all by myself.  then I met him.  He was an exact copy of my dad as sick as that sounds, but the devil you know is sometimes comforting.  The violence started almost immediately after the marriage.  At eight months pregnant I was rushed to the hospital with broken ribs terrified I'd lost my child.   I thankfully did not.  He was born early but he was okay.  I have this house because I bought it with my own money and moxie when I was 19 and insisted on a pre-nup. It was the only thing I had and I didn't want to lose it.  

  I stayed because he threatened to take my son to costa Rica where I would never see him again and he had the connections to do it.  It was only after a particularly viscious attack that I knew I had to go or be killed.    My ex has never paid support which would have paid taxes and upkeep.  I was threatened with death if I went after him for child support even after he signed a separation agreement for child support.   He is a dangerous, dangerous man who has spent time in jail for spousal abuse.   I chose not to pursue him financially because  I am still terrified of him.  There were many, many injuries.   Due to several head injuries including a skull fracture, body injuries and severe emotional disturbance that will keep me in the care of a psychiatrist for the remainder of my days I am unable to work. I am physically in horrific amounts of pain all day every day and most days due to my psychiatric problems  I am unable to go outside.   I am on a fixed income which does not allow for things like property taxes or roofs or doors or ovens or couches or things like that.  I'm in desperate need of help or believe me I would not be asking.  I just do not know what else to do.  anything will help. Anything.  5 dollars is 5 dollars I can put on my taxes.  every dime I put on the taxes shows I am at least trying to pay.  Thanks for reading and I would appreciate the help
