Michael, Illuminata wrote an excellent description of the Piecing skills needed for the LBS. I think all posters new to the Piecing forum should review it. It will highlight the skills needed for you.
I understand your disappointment regarding your W's recent actions. The challenge is to be disappointed without spinning into negative thoughts that keep you unbalanced.
It sounds like healing is occurring in your M right under your nose. Hold onto your hope that things will get better, and faith in yourself to navigate this phase.
