Short Phrase Translation Help

[Verurteilen]

I need some help on a translation for a potential tattoo design (hence the super triple checking). Having not been studying the Tolkien languages very long, I would rather not attempt this one on my own.
The phrase I'm looking for is:
"I was never worthless." (Or, for alternate phrasing as necessary, "I'm not worthless." )
A translation into Quenya with explanation would be greatly appreciated to compare to the (potentially incorrect) ones I have been given before or tried to pull together myself.
Thanks!
