Re: does molluscum ever go away??
The virus can remain latent in your body and keep causing new bumps until the immune system finally recognizes the virus as the pathogen that it is. Focus on general health, exercise, sunlight, healthy eating, maybe eliminate sugar. And I would probably avoid taking any supplements because it's really hard to know which ones would help or hurt the immune system's chances of detecting the virus. (I've found a lot of people say that some extremely immunosuppressive things are immune boosting, so I'd just eat well.)
You might go back to your doctor or go to a different one who is comfortable using some irritant treatment on them. I'm not sure what it is that doctors use for this, maybe low concentration cantharidin. (This might even be the same as some home wart treatments, but it's probably slightly stronger.) This irritant treatment is more likely to stimulate an immune reaction which results in immune recognition of the virus.
