Hi,
I am a PhD student, finished the 5th year. I spent the last two years writing the thesis as the supervisors advised me to do.
After writing the 1st and 2nd drafts, the supervisors said I should add more experiments to the work.
They suggested some points I mentioned in the future work and want me to do them. I asked them if they already had some ideas, literature, assumptions, and expectations, and they answered no, and this was part of the research.
I have suffered enough last years when I started working on the project. They proposed a topic without being aware of the difficulties, and I spent all the time frustrated alone.
I do not know what to do, I do not have a research community to get ideas, and I do not believe my supervisors know what they want. Few months left for me to submit my thesis.
The last time I tried to talk to a professor at the university, he told me that I should speak with my supervisors.

Any advice on how to resolve this?

Thanks
