I don't have any help or caring family members, alot of them and self centered. Why would they be unlikely to get me back in? The property isn't in her name and it's not on the deed.If you are locked out, call the police. While they are unlikely to get you back into the house, they can get you to a place of safety until you get a court order. If you are in danger, the police might even remove the person threatening you so you can get an order of protection.
Unfortunately, you have a lot of issues colliding. I hope you can find a family member or other advocate to assist you. If you are a member of a religious group, contact the leader of it. Many have resources among their congregations that could be of help.
