I'm doing my MSc. in Computational Mathematics in Central Europe. Right after finishing my Bachelor's degree I began to work in our National Supercomputing Center, a research institute that is associated with the university where I'm studying. It is considered quite a prestigious position in my country. Because of this offer I quit my job in the industry.
At first, I was enthusiastic about the research topic and after several months I was assigned to the second project (completely different from the first one).
This job began to consume almost all my time, so I gave up all my free-time activities and devoted myself just to this research. Because of the amount of work here I got into some serious problems with school projects and exams, but, so far, I managed to pass them.
In the first project my job is the implementation of some direct solvers, but some time ago we found out, that the technology used in the implementation is not suitable to our problem at all, so this solver will be useful just in some special cases, or possibly, it'll be unusable at all.
The second project appeared well - we managed to write some papers and tried to publish them. This week I found out that all of them were rejected.
Now I feel terribly disappointed and inferior to the others. All my colleagues have some publications, because, their other projects are usually successful. I'm working on two projects, where both of them are now just a waste of time for me, because I'm not going to have even one publication from them.
Normally I would try to discuss this with our team leader, but, to be honest, I'm scared to do that. He's not very sympathetic to the fact I'm still studying nor to the fact I'm there just for part-time job, so I shouldn't be working this much. I'm afraid he'll simply tell me, that in my position I should be glad to be working there at all, or something like that.
I'm not asking about some "improvement" of my personal feelings, as in How should I deal with discouragement as a graduate student? - I'd rather like to know, if it's a common situation and if I can ask to be assigned to another research topic (I have no prior experience with research, so I don't know if it's considered impolite etc.).
