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. ==
