I'm sorry, I can't think of anything to do but holler for help!! Any teenagers in the family that you can recruit?
Maybe you'll get lucky and whoever helps you will get "bit" by the quilting bug and become a new quilting buddy?
(Sorry to hear you got mugged...how awful!! I got robbed once, at knife point, but thankfully I had a weirdly polite robber - when he figured out I was a broke teenager with all of $3 to my name he didn't even take my wallet. Just told me to turn around and run, which I promptly did! Scared me half to death though!!)
