I've been going through some really bad terror episodes for the past few years, I get scared of my surroundings pretty much daily at this point, things like home intrusion or getting murdered make me feel threatened everywhere I go, even though I know it wouldn't happen. Facing it head on makes me feel like passing out, I get sweaty, teary eyed and shaky, this happens with the littlest things, like calling a teachers to discuss something. 

But there is nothing that would trigger this. I've had zero experiences or trauma that would make me so anxious. Can anyone relate to such a sudden rise of anxiety? I just feel so horrible-
