Friend's crazy mother kicked me out of her house and kept a lot of my stuff...?

Well I'm on break right now and my mom had to go out of state... well my mom asked her good friend if I could stay with her for the week and she said yes. Her daughter wanted me to bring over some stuff, ( laptop, xbox... ) and some other stuff, so I did. I went over 2 days ago and everything was fine. but earlier today she told me to say grace before we ate, and i didn't know what to say, so she looked at me all weird and went " aren't you christian? " ( she is very religious ) and I said no, and she UNLEASHED THE F**KING FURY and threw me out of the house, while her daughter and husband were just sitting there freaking out. She told me I can't get my stuff back and she was gonna sell it. I don't have anywhere to go because they live in another city, and I can't call my mom because my phone is in her house, and I don't know my moms number. So, I've got no where to go and I'm sittin here chillen in the library. What do you suggest I do now?
