There is no accounting for the lack of respect people have when it comes to asking questions they have no right to ask. I think some of it comes from being curious....as humans we are a curious bunch. But there is a clear difference from being curious and being judgemental and in many cases ignorant to many things.
I think one comment from you to them when they start asking questions would get them to stop and that would be, when you are asked a question that the answer is truly none of their business...ask them "And why do you need to know?". Some will come back and say they were just curious, others will start fumbling around because they know they are being nosy and judgemental and you just called them on it in a very reasonable way

You can ask that question very nicely, without any negative tone in your voice. It will more often than not, will stop folks right in their tracks and they will not question you further. If they are inconsiderate enough to continue asking, all you have to say is "The answers to that question are on a need to know basis, and you don't need to know". Again, saying it nicely without a negative tone and then just walk away. Simple as that. People will get the hint
I'm sorry you are feeling like you are being judged and picked on. And I do know that sometimes people truly do care about us and question why we do things differently than they do. If it's ever a matter of doing things differently you can always inform them that there is always more than one good way to do something and that this works for you

(then smile LOL)
