I wouldn't necessarily say that you are that contagious. Nano-tech mind control can make people say or do whatever or act however. Do not blame yourself. As strange and crazy as it sounds, we're all being tested and it sounds like that is some sort of spiritual test. Once you 'pass' whatever it is, things usually get better.
If you are open minded you can look at it from this perspective.. http://www.dataasylum.com/targeted-individuals-cure.html.
Try to find truth and a spiritual center, in whatever way you can and it should be easier. Even as an atheist with a contemplative grounding you could get them to stop, you just might be a little incredulous at the results.
That site has only had that page up for a month, so that form of 'cure' is still kind of new, but if V2K, TI programs, and Morgellons are the same, it would be the same. I prefer the spiritual cure myself.
