Sorry you are having such a hard time. I took an 8-week course for FMQ and we used the book "Machine Quilting Made Easy" by Maureen Noble. She has lots of exercises in the book and they certainly help you figure out your machine. All I can say is give it a try and use 12-15" pieces for practice. That way you can focus on the technique NOT the quilt.
I started using a vinyl sheet on the machine to help cut down static build-up. It is worth the expense to me.
Good luck.
