I think in order to step up your game on RU-vid, that is, making non-vlog videos on a regular basis, it's doomed to become stressful like that unless you're an ever-flowing fountain of intricate ideas. I've found that recently, though if my depression would only leave me be, I'd put up with it because in the end, the payout tends to make it all worth while. I think. Potato.
I'm sure the dry-spell you're going through will end soon enough, sooner than you think. Perhaps you need to find anther method of coming up with videos, perhaps writing down random things or talking to someone who you think might help get your brain juices flowing.
When you spell mentally with three Ls you know you are having problems. I can understand the reasonable doubt of one L or two, but three crosses the boundary into wrong on all counts - There can never be three consecutive Ls in the english language. Things must have been tough for you.
