How does the Energy of a particle stay together?

How does the Energy of a particle stay together in a sphere?

Unlike photons, particles---electrons, neutrinos, quarks, etc-- hold onto their energy. But how? I use to speculate, thinking that maybe photons could fluctuate into some sort of endless ring/sphere of infinity creating a particle... but I'm really not sure.

They are not spheres. They are structureless points (in SM). They don't need anything to hold them together.

Well what causes energy to stand still in particles vs move and cover distance as in photons?

Energy isn't some physical object that can move around freely. It's a property of particles or systems that is conserved.

I don't understand your question.
I understand every word separately, but not the question at whole.
Are you asking about the difference between particles without rest mass (photons) and particles with rest mass?

Yeah that's what I'm asking
