Look on eqplayers, and search under your character name. They should still be there. You don't need to have an active account to log in.
If they aren't: they may be an a different server. Characters were moved when servers were merged. Only characters under level 6 that hadn't been played for more than six months at the time of the mergers (February 2005) were deleted. Characters on a new server where a character already existed with the same name will have had "x"s added to the end of their names - several, in some cases (I had a character with three x's). Renamed characters can /petition for a free name change.
If you gave your log on details to anyone else, then you shouldn't be surprised if your characters are missing, moved, deleted or just stripped.
Deleted characters can be restored, even after a remarkably long time. Just ask very nicely (in /petition).
