I'm sure I'll never get the false cord scream

Yep, I tried all tutorials I could find, no matter the search all videos will appear as watched because I did.

Moved from platform to platform, completely useless.

The thing is, EVERY tutorial ALWAYS use at least one of these examples: sigh, bark, frustration, calls, cough, bear, clear your throat, yawn or sheep.

I never got any, I always (and I mean it) end up hurting my voice, no matter how relaxed, low or controlled I am.

Worst of all, I cant even get myself at coach.

Ive seen from adults to literal teens get the false cords, i'm sure I can too but im just stuck.

Anybody can help me out please?

Thanks in advance.
