This kinda thing happened to me and I made the 
mistake of being nice and telling the person about 
it.  From the emails I got from her, I thaught she 
was going to go into cardiac arrest and I am only a 
psych major, not a med student!   I eventually 
calmed her down by promising to put her in my will, 
but every once in a while I still get a begging 
email (are you dead yet?)...  ^_^;
