I wish you were near Denver, I would love to try to help you getting your machine sewing again. It almost sounds like it just needs a good cleaning, lube and maybe some adjustment. Sometimes, it truly is just something simple. I'm going to refer you to

Are you threading the tension with the presser foot up?

Have you taken the bobbin case out and cleaned around the feed dogs?
Is the bobbin case holder in the correct position and tightened down?
