In the final month of work before writing the thesis I found a bug in something I did a couple months before. I talked to my supervisor and we checked together that indeed something was off. I took full responsibility and corrected that portion of work.
This way I lost 1.5/2 months out of 6 (where the firsts were only about studying) and I now notice that I really lack content to write. Those lost months weight a lot and are not salvageable. They were the part of the thesis where true work was done.
I don't know how to say this to my supervisor. He is continously pushing me to just write the thesis, but I'm quite sure it's just a way to end the project since, independently of anybody, it was a dead end from the beginning (he admitted we have no idea how to keep going).
Probably those months would not have been that big of a problem if other things we tried before had worked. But the whole idea behind the thesis resulted in a dead end and more time was lost without it being anybody's fault.
I really need a good thesis for PhD admissions (here it counts a lot) and right now I don't have it
Add to this a not exceptional relationship with my advisor,mainly because as soon as this project showed up as a dead end he lost interest, and I think he was (understandably) pissed by my error and really stopped answering to many questions
I'm not exaggerating when I say that much of the work is just a rewriting of well known facts and the new part is very very small and definitely not fine even for a MSc thesis.
Should I consider the possibility of dropping the thesis if in no way my supervisor will let me work a couple extra months to produce new material? Would this make me a selfish student?
I am really embarrassed by my mistake. It was very dumb and I suppose I gave the wrong impression about myself. I chocked under pressure, I guess
