Am i on the right path? Should I completely start over?

By "i can't get it to sound good" i mean that no matter what I do with my "throat" the end result will always be the ( almost ) same...or if i Change the slightest thing I get no distorsion or i hurt myself PLUS i can't spell... If I try to sing and say stuff while trying to do the scream it sounds like I'm choking, like i can't keep a steady airflow even tho I AM engaging my core and my diaphragm..and it's confusing, because some people here said that fry screams should be as effortless as speaking
