There's a long standing bug in the game that was never fixed with an official patch whereby if you get inflicted with a disease or otherwise have an attribute reduced while wearing an item that boosts the attribute then no restore spell or potion will work properly.
So first try taking off any item that boosts willpower and take a potion or cast a spell to restore it and/or visit a Tribune Shrine and get an Almsivi (sp?) blessing.
That's assuming that when you take off boost items the attribute is red on the character screen. If it isn't then there could be something else involved, and that would baffle me.
Something else you could try is using the console if you're playing on a PC. I think the syntax is player->setav willpower ##, which if my memory isn't buggered would see you willpower set at whatever number you used instead of ##. So if you typed player->setav willpower 70 your willpower should be set to 70.
Apologies if the above is not helpful, it's been a long time since I played the game.
