I'm a student at the end of my degree and I'm also at the end of a not so good internship where I developed my thesis. I don't want to bore you with the details of my internship, so I'll just summarize it.
In the begging the conditions were good, I learned a lot and made good progress. After two months (of six) my supervisor started to treat me poorly, every week he found a new issue with my work. He deliberately gave me wrong data and he began to try to intimidate me by saying things like like "Do this, or you'll not be graduate" and so on. In spite of this, the quality of my work remained high and a lot of my colleagues gave me compliments about the level I had reached. Even my supervisor was forced to admit the results achieved were good.
I have just few weeks left or my internship, which are reserved for writing the final thesis. I have already written the first and second chapters and sent them to my supervisor. As expected, nothing was good enough for him, he just returns mt progress with everything underlined, saying that everything needs rewritten. He is trying to intimidate me again by saying "Write your thesis my way, or you'll not graduate".
So, here is the problem. I believe that writing is a really hard task for which you need a lot of focus for and to remain in good spirits, but with someone that everyday disapproves of your work without justification, but no guidance, it's really hard to move on. Everyday I think that what I write is not good for him and really affects me. Most of all, I'm worried that at the end he will not approve of my thesis, I will have to start again with a new thesis.
How can I deal with this? There is nothing that I can do to find the strength to go on?
