Hello!
Thanks for writing in. I totally get and understand wanting to limit screen time on your devices or limit time spent on social media apps. It's great you're seeking ways to find help about these issues!
I personally have been able to just turn on a YouTube playlist of like a Let's Play as background noise and fall asleep. Some maybe unable to do that, and it generally does help me fall asleep with ease.
What I'd maybe suggest doing is just putting your device in another room to charge where you're not tempted to look and browse YouTube shorts or any other app. As someone else said, just deleting the app could be useful too.
I honestly don't really get on my social media apps much on my phone or
PC anymore. I've found them to be places that are more negative than positive for me.
