Thanks for your answers! In my department, almost everyone sent in an abstract, and most people started even later than me... But they all got accepted. My supervisor read the abstract and corrected it a little bit, but he really isn't that much of a support, I hardly see him because he has so many PhD Students.
But lately, I have the general feeling that all people around me know so much more and see their supervisors more often than me. But yeah, maybe it is just too fast...

I applied for my first conference and got rejected :-(. The reviewers had no remarks so I don't know why. I'm quite disillusioned, since I have the feeling I haven't achieved anything yet since I started in september last year, and all the people around me seem to got accepted for this conference (it is quite a large one). I really feel like a failure now...
