hey dude,
This is never something easy to tell a vocalist, but sometimes there is so much damage to the vocal chords that the voice may no longer be able to produce even sound. This is the result of many years of (sorry to say) poor singing technique, which is almost every metal singer/growler, so don't worry it's not just you. What has physically happened is that you've strained your vocal chords by singing too loud, and to try to repair themselves your body has formed scartissue on the vocal chord. Scartissue changes the vocal chords' tension and response to passing air. The only thing you can try is to not sing that way for a very long time, perhaps a year, or 5, 10, or never. Most of the time these wounds are irrepairable. Sorry to bring the bearer of bad news, but I've seen many vocalists go out this way. OR you can just be sick... haha if that's the case, be forwarned that this happens often with metal singers. Good luck with everything
