I am taking deep breaths. I am changing how I'm supporting the wall edges though along the wall opposite the dinning area. Instead of Trying to attach to a floor joist with 3 or 4 2x6's screwing one into the other, I'm going between two joists and use 18ga. joist angers on the ends attaching to 2 existing joists. May not be correct, but I think it will work.
