If you added up the mass of all the electrons and quarks in your body it would only amount to about 1% of your mass, 99% comes not from the Higgs field but from the binding energy that keeps the quarks inside the protons and neutrons because, due to E=Mc^2, we can equate energy and mass. Neutrinos also have mass, its much less even than the electron's but its not zero, and nobody knows why, the standard model can't explain it and neither can anything else that we know about. > > The* fundamental* unit of mass is the Planck mass > Maybe, maybe not, some theories say so but there is not a scrap of experimental evidence in support of the idea.

The only thing it has to do with gravity I know about is if d is the Planck length then the energy in the photon is so large and is concentrated into such a small space that it becomes a Black Hole. Quantum mechanics can't tell us what happens if d is smaller than that and neither can General Relativity, that's why we need a quantum theory of gravity.
