So just to give you an example of a delusion...for example you might believe that you can save the world from an impending invasion of dragons by doing certain things or that you can stop the voices by doing certain things for example putting all your computers into sleep mode. Rationally you might ask how would putting your computers into sleep mode do anything? Yeah that's exactly it ...it wouldn't but what you're thinking actually offers a potential solution that could in some circumstances work and that's why I think it's inherently different. If you want to feel more reassured you should ask your doctor.
