Pregnant Dealing with harassment?

I'm unsure of what to do but I am currently dealing with harassment from my live-in MIL. My husband and I are currently in the works of finding a new place without her and in the mean time are stuck with her because she has nowhere to go and has been living here for over 3 months. I am 9 months pregnant and I have epileptic seizures that are made worse by stress. She will do things like throw my clean clothes in the floor, take my food from the cabinets and put it somewhere else, so I can't find it, she's thrown my dishes away, and alters my food if I leave it out or don't finish it and leave it in the fridge. She does it I'm aware to get a rise out of me and my husband so she can call the police and have me arrested. She has lied and told them I've slashed her tires, and I threatened to kill her two times already. Then she'll threaten my husband and block him in the driveway so he cant go to work or hide his keys. I'm at the very end of my rope, I feel like I'm about to have a nervous breakdown which Im sure will have a bad affect on my pregnancy, but I don't know what to do. If he says something to her, she attacks him, I never say anything to her because she only verbally attacks me. Is there any way I can get her to just back off, like a restraining order saying ok you can live here, but don't touch her things, don't speak to her. I don't say anything to her, every since she became like this towards me, I do everything to avoid her, but its affecting my health and I don't need this right now. If I could leave I would but my money is tied up in purchasing a new house. The home I live in now is in my husbands name, he purchased before we married. I live in Georgia.
