I would rip it out because you aren't going to want to use it like it is. It's probably not something you even want to donate. Maybe set a goal to do one quarter a week and in a month you will be ready to quilt it again. Good thing she didn't charge you a big price for it. Just get it out and start to take out the stitching. It will probably make you feel better to start the recovery process. So sorry for you!!
