It’s only the second week of the summer semester at the university and I’m already dead tired. I’ve got so much work to do, many essays to write and so much literature to read that I don’t know when I’ll do it all.
I’m psychically tired because I’m worried if I’ll manage to do everything that I’m supposed to do and I think about it all the time. I can’t stop worrying and consecutively I can’t fall asleep in the evening. And that’s why I’m physically tired.
