Buy yourself a white noise machine. I’ve been using one for almost 10 years, it’s helped my sleep routine immensely. I prefer it to something with talking because the fluctuations of something like comedy would disrupt me. Also, I think that concentrating on something like comedy makes me want to watch it and I would woke up.
The next thing is an eye mask. Even if your room is mostly dark, I’ve found it helps me to stay asleep.
I don’t see the poster explicitly complaining about getting downvoted. How I read it is that they think that downvoting encourages people to be negative and weaponise their downvote. And, given what you’ve said, they’re spot on and you inadvertently proved their point.
