Can't let 'em 'stick' to you. Smile and nod, give them a like
   emoticon, a good luck, and then find someone more mentally
   stable. Coping skills then. Let them talk it out if you have to
   engage with them but keep your "self" separate, as if you were a
   physician and they were a patient but your job isn't to diagnose
   or treat, just to observe. ==
