Not feeling particularly well today...

Sometimes I have this overwhelming feeling of not being able to cope with my life - or more specific: with my studies - at all. I feel that there is so much to do and there is just no way that I will be able to do all of it in a way that I'm satisfied with. Right now there are to exams ahead, one of which is super-important and the other one, that is just 3 days before that one, is also really important because both of them will partly determine my final grade - the one first mentioned will actually be 1/8 of my final grade. This is usually enough to freak me out anyway, but then there is also my thesis, which I am kind of starting, or not, I don't know, because everything isn't very organized and I don't really get what the guy wants from me or where he wants to go with the whole project. He's a great guy and he basically treats me like an equal, which I think is a good thing, but which is also kind of overwhelming and stressing me out. I don't feel competent enough for that. And then we agree on things I should do and when I get home I realize that I don't have any idea what exactly those things mean and I'm scared that everything I do is wrong. Moreover there are like five million other things I have to do for university - well, not five million obviously but I have a presentation next week which has to be finished on friday (today is wednesday) and I have literally not even read through the papers and stuff we are supposed to use. Plus, one of the people who is doing the presentation with me isn't even in town right now and will come back, like, one day before the actual presentation or something. Also, I have to present an interview I had to do next week and also hand in a 4-8 pages final report for another class, which I still have to write completely. And somehow I have to find time in between to study for those two exams in february. I already started to study for one of them in november or something and I haven't even worked through 1/3 of the content. How am I supposed to do the rest in 1 1/2 super stressfull months???
