spleen

We have finished our exams, and at the same time the course-part of the PhD. Now comes the real research part.
I am glad that I reached that stage, but at the same time I feel now empty, I am in low spirits. I think it was worth doing everything up to this point, but I am not sure about the future. I know that very-very probably I will finish it, because I am not of the kind of people who gives up easily, but sometimes you just get fed up with it.
I know that every people in every job, every country etc. has his/her downs in the life that is why I do not want to overdramatise the situation.
As I began PhD, it looked a sort of adventure, but now I consider it a very serious and important thing, which determines my life with respect to future job, to postponing such important things in life like marriage etc, and that makes me a bit tense.
I have the impression that my mates have the same kind of thoughts these days, let´s see if they comment on it.

I finish yammering around and go back to work.

Thus, Phd rules, but it is not a bed of roses.
