Thanks alot everyone. I got a smoke detector yesterday. No one knows how the fire started. There were batteries in my backpack, those are the only things we can think of that may have caused a fire, but we don't know how, they were all fairly new batteries in good condition. My friend asked her mechanic boyfriend and he said it would be extremely unlikely but not impossible that if the batteries were to combine positive ends in the right way it could have caused a spark, but even then the spark would probably be too small to cause a fire. We did have a lightening storm the same day, perhaps static electricity in the air caused something??
I couldn't call the fire department because my phone was in the livingroom but I didn't know where. My kitchen is right next to my only exit, I wasn't about to go all the way back through my house to search for my phone..If I had left it for only a second it would have gotten to my cupboards, it was a good thing I stayed where I did and kept pouring water.
I need to get some baking soda as well, the last time I had a small fire (my oven had some food that fell down and lit on fire) I was going to get some baking soda and I just haven't gotten around to it.

I talked to Jynnelle lastnight, she is still on morphine so she doesn't feel any pain. She is on an IV as well and they gave her a gravol shot because she is throwing up. They took some blood as well. They took x-rays today to see if she has kidney stones but I haven't heard from her yet to see if it was positive or not. Hopefully she'll get back to me tonight, I'm so worried about her.
