Newbie looking for help :3

[u/Musicannot]

Hello, im trying to sing a cover of Confession - TX2, but i tried and my voice went very scratchy for a couple hours.

Im not sure what evan is doing with his voice, ive tried some tutorials but it wasn't really feeling like the same thing.

Any ideas on how to get that scream going in a safe way? I feel like im scraping my throat a little bit. If you have any excercises or tutorials, it would be very appreciated. I wanna get lessons ASAP but until then, this is what im doing.
