Okay, here's my suggestions.
1. NEVER, EVER try to live without a back-up machine.
2. Learn to clean and oil your machine, once a year isn't nearly enough. It's not rocket science, if I can do it so can you. Just take that plate off and put a drop of oil on everything that moves. Take an inch square of polar fleece and a some tweezers and swipe out all the lint. Put it back together and VOILA!!!! You've done it.
If I'm sewing everyday my machine gets cleaned and oiled at least once a week usually twice. Depending on the fabric I sometimes clean it every day or twice a day if I'm working with flannel.
You can do this, just take a deep breath, smile, tell yourself that you can do it, breathe again and have at it. If nothing else, ask a sewing friend to show you how.
No one should ever have to live without a sewing machine, that's referred to as CRUEL AND INHUMANE punishment.
