I have a day off today. Thankfully I have 2 things scheduled which makes things easier. But I have to study for something in between. I woke up afraid. Do I cook first? What if cooking is going to contribute to me having less time to study? Well I can have breakfast and cook simultaneously. Then, I'd start realizing that I actually do have time to study. Then, this makes me scared; wow something should go wrong, will I really be able to finish the material on time? No, something bad should happen and disrupt my control over my self and my schedule. I worry about not having enough time, but also now that I am realizing that I have time and already know stuff, I am more scared. I don't know what I am scared of. Worst case I will fail the exam. I can retake it. Also my life doesn't depend on this exam, it's just something that I decided to take. 
I am worried about things going against how I planned. I am even worried about things going the way I planned because then something bad should happen. 

Then I start worrying about the fact that I feel content and have the energy to do things which also means something bad might happen. Then, is this a premonition or just anxiety? 

I didn't know that that was part of anxiety. I thought it's a normal way of being and existing. Is it really anxiety?

I guess I should start doing things instead of overthinking them. Whatever happens, happens. 😀 

Then I even start worrying that I will suddenly loose motivation and energy to do things or to study. Like I will loose control of my own decisions and will. 

I don't know. That's how I deal with time off. Except that I usually exercise and do healthy stuff but now I have to study for this exam so...
