I've been in your situation before many years ago as a new muslimah in rural southern California desert area.
Our town was very small mostly migrant workers there was an airforce base close so although there was on base housing we had reserve families in our neighborhood.
We lived there for 9 years and it was almost 6 years before the area started to grow and than before we moved to Michigan we just started seeing more muslim br's and sr's around town. So yes I know how tough that can be.
I would suggest utilizing more of your online resources for added support. Not only are there many good sites to help new muslimahs like yourself but also sr's only groups...try going to yahoo groups and type in muslim women or sisters or new muslimahs in the search box and Insha'Allah you'll find many groups.
Also you have this site here.
Another good source more for socializing is muslimspace.com. Although it is mixed in company so you might want to put a little blurb on your the page that it's intended for sisters only.
Hang in there it's always tough when everything is new and there's not too many people around you practicing the same way of life...
Remember what is truly important to you and ask Allah(swt) for guidance he will never abandon the believers.
