Not sure there is much interest in teams outside English Primula/Championship level, but here goes, oh and remind us of the object of your misery. (This has been mentioned in other threads but no harm in reminders!)
Mine is Northampton Town, they have been up to the top league in England, but more often than not, can be found in League One or League Two. Perenially used to finished bottom of the league and had to seek re-election to the league, had the only 3 sided ground in the football League. Nickname the Cobblers.
More Recent history, beat Reading and Liverpool in the League Cup, highlights of an otherwise miserable season.
Current Manager Ian Sampson, a LONG time servant of the club, who, in all honesty, probably would have been sacked by now, if he wasn't so loyal to the club.
If the thread dies a death, don't feel bad, I am used to disappointment!
