Hey, in the end I figured that these were simple fears of a really close person. probably that's why the shield had let it through.

though I have found a new way to stop it. some time ago I read on this forum something about a symbol you develop to ward off negatives, the guy was speaking about an idea of a large and shiny light cross that he pointed towards the area that was neg-affected.

so I figured that I should try a symbol that makes sense for me. and so it was - the symbol I chose really didn't allow anything to come inside me. even when I witnessed that person's hysteria, I could stay perfectly calm and it could not move me. I could even help the person, by sucking all that negative energy into me through that symbol - it didn't affect me and she was cleansed as well.

though this hypersensivity is not a sweet thing sometimes...
