Aloha LindaJ,
Good questions. The Gold edition is set up the same as the Level One section of the Silver course, and after a front door reading and some information about the purchasing/renovations of your home, the time feng shui is simple and straight forward.
Since I can't address if your situation is being hindered by time feng shui energy or if there may be dowsing issues involved, but in regards to the general space feng shui I have a couple to get a little better look at your situation:
What changes have you made and when?
From the letter I only know that you've had the course for 6 months, but not what "done a large number of activations" means specifically. The "when" part can help give more insight as well, since the general space feng shui in Levels One and Two build in impact and energy over time, and aren't as dynamic in the short term as the time feng shui.
What couldn't you change or work with?
Things like: Were you able to have your bed and office desk face a good personal direction in a supported way? Does your front door face a favorable direction for you?
Then we can go from there.
Much Love,
Shawn
