cant sleep what to do

What does one do if they cant sleep because they just keep doing things? Because if you stop doing things that distract you, you have a chance of a thought occurring, and thats horrible. You might end up pondering about your life even.

So yeah i just keep either looking at things on my phone, or reading, or playing videogames, or anything to distract myself. And i do get sleepy, but i cant really stop what im doing because im just too scared to stay alone with myself/face reality.

And i dont get sleepy enough so that i just black out. Im doing pretty fine with low sleep so far.

yeah thats the question. sorry if its silly.
