How do you deal with Burn-Out during the semester at Uni?

Hi guys

I've been feeling kind of tired for some days. Always right after a lecture I have to go to sleep, I actually do nap for a time so I'm definitely being sleepy here.

I also lost some of my motivation when it comes down to some subjects, especially as its gotten harder and harder which is normal because it's always easiest at the beginning of a semester.

Now I find myself in a situation in which I absolutely feel the need to chill and rest, which I do. But there's also another side of the story

The reason I need the feel to "chill" is because I believe and know that my obsessive and intrusive thoughts about some topics (like having to go through the same problems or situation i experienced in the past which were hurtful) would get worse if I would force myself to do which is something outside my comfort zone, in this case studying

That's why I try to be as chillaxed as it's possible. My room is dark and only a small lamp at my desk is lighting, I had to install windows 10 recently so I keep it "as clean as possible", I even use Bing because it calms me down (idk why, I guess it gives me the patience to actually search for the right thing instead of using Google and unconsciously clicking everything), I also started to use a fountain pen with dark ink

It's an environment which allows me to do at least some work but if I look at my mates which are the best of our class and maybe even our year, they really study the whole f*cking time (they even sometimes sit on an exercise until 4 am)

Of course I'm jealous of them, but this just let's me to think how I could become at least somehow like them, and also be a workaholic like them. I'd be more satisfied with myself, because I could at least say that I've given it all, regardless of the result in the end

So what are your tips to transform into a workaholic?
