Do try to get a local person from high school/quilt guide to give you a hand. Once you begin, get a large 3 ring binder and make something with every stitch in the machine and put it in the book (stitch #, size of stitch, thread used, etc.). The book then becomes your guide to what the machine can do and what you have to work with.
Practice makes perfect and so does patience. The trade off of lunch or dinner sounds great if you can do it. Just take your time. When you do get frustrated, get up and walk away from the project until you cool down. That might mean you don't sew for a day or two but then go back and finish it.
Welcome to the wonderful world of sewing. I have been sewing for over 50 years and still learn something new when I make an item or replace or redo something.

PS Just finished redoing two flightsuits for wives for dinning out on the base. Flightsuits are not meant to come apart but I got them apart and put back together into nice dresses.
