Can't remove negatively charged debuff

I have this debuff https://www.wowhead.com/spell=440390/negatively-charged that keeps refreshing and won’t go away, +20% damage taken all day long is a problem

Try getting your character killed. Or enter an arena skirmish that should clear buffs and debuffs.
