I don't know what to do...

My fiance has an eviction on his record, so we've been living with my mother so several months now. We became pregnant while living with her and she was estatic seeing as its to be her first grandchild.                                                              

July 4th happened. I had a car full (myself, my fiance, my brother, and my brothers boyfriend) when we were out camping with my mother. Well inside the car someone made a joke, to which point I was laughing at. My mother walks up to the car and automatically assumes I'm laughing at her. She tried to ruin the trip, but the 4 of us still did the activities we had planned, she just refused to join us.                                           

Now a week later, today, she walks into my bedroom and tell me "I cant live like this anymore. I talked to the landlady today and your brother (who is mentally handicapped) and I are moving back to Indiana in November.                                       

Might I add, Im giving birth in December. I told her that she's throwing a fit with no reason to be. That she just thought I was laughing at her and that she was acting just like my father (my father used to ruin every family outing because he'd throw a fit and my mother would argue). She tells me "well I see the truths are coming out" so I told her if she does this, she wont have a grandchild to see. She then has this creepy wooden doll in her hands, proceeds to behead it by banging it against the wall, and throws the bottom half of the broken doll at my stomach.

Back in May, I quit my full time job due to sexual harrassment from being pregnant. She told me to get out of there. Now I'm working 3 part time jobs and not making nearly enough money. My fiance works full time, but he's a cook at a restaurant.

We cant afford a place to live, nor can we get a place with his record and I'm pregnant and feeling helpless. I don't know what to do. Any advice would help at this point.
