Hmmm intriguing... Maybe I'll just find a way to insulate the circuit. Might be less troublesome. Than finding a negative regulator.

My previous post shows a link to an LM317 (1117 = same concept) circuit used on the negative side.

Here's one I found here in LPF by Wolfman

No worries I'm looking over it now, just thinking that might be easier on my part. Rather than flipping the whole thing around. I'm horrible at reading these things lol that and I only want to use one driver on the circuit.

The concept is the same. The circuit posted only used two in parallel since it's a high power diode. you can use one in your application.
