Whenever I stay up late on my phone or even just staring at the ceiling, I get nervous. 

I’m not thinking about anything particular when I stay up late, just trying to finish up a game on phone or relax enough to sleep, but I just start to feel horrible

I get a headache and my eyes start to hurt and I start sweating and I feel nauseated. The later I stay up the worse it gets and it just feels so overwhelming.
