Do particles de-excite in their corresponding field and vanish?

I am not a physics student. So, please accept my apology in advance if this is a stupid question.

I read that particles are the excitation in the field. So, when electromagnetic field excites, it produces a photon. Similarly, electron field produces electron. AFAIK, excitation means increase in energy. Is it possible that reverse also happens? I mean, electron just disappears into electron field forever. And what is the source of all these fields like Higgs field, Quark fields, etc. Has they been present since the big bang?
