Re desperation/difficulty in finding a job - there are people recruiting who don't care, to whom all that matters is the ability and whether you're easy to get along with. If you get upset about not getting a job there's no need in being even more upset about being upset ;).

IMHO: People go through various things in their lives and troubles are often just temporary and if someone's going through hard time it doesn't have to indicate there's anything wrong with them.
