After much measuring, and attempting to move my bed, it seems there is no way out of this dilemma. The bedroom itself occupies two squares, but the bed unfortunately, has to remain in the middle, so shares a 1 6 6 and a 5 1 2 configuration. What can I do to mitigate the 5 1 2?

No offence, please.
If qi can be clearly defined as splitting between an invisible line along a bed; this means also that "pigs can fly".
Fortunately, you are (partially) correct to look at the worst and think of the bad numbers.
However, as I had previously mentioned; if one were to apply Flying Star Feng Shui it is like an engineer or a technician using smoke to look at how an object behaves in a wind tunnel environment. (Again not exactly the same but...)
One has to see where are the openings especially of importance are such things as the window(s) and even the room door.
For example, the split personality bed and 5 1 2 lies close to the corner furthest away from the bedroom window or the bedroom door; then greater influence goes to 1 6 6 etc...
For 5 1 2: the main thing to avoid is the use of YELLOW especially avoid bright yellow curtains or bed sheets or even warm white lights etc...
Let's hope that Feng Shui has not gone to the dogs.... if not...
