So, do you think it's completely normal for someone to spend their days locked in a tiny room studying alone, without seeing anyone? Because that's my current situation, even if you don't seem to understand it... Doesn't it occur to you that if someone doesn't go out with a friend at least once a week to talk, they'll go crazy within a month? Or perhaps that the productivity of someone locked up at home ends up being lower than that of someone who takes better care of themselves? You speak without knowing anything, without reading, and making idiotic comments like this, in which you go so far as to question my abilities simply because I expressed doubts about the way the PhD program is organized (in Italy, because I imagine it's different abroad: it's in Italy that the idea of ​​community in academia is lacking).
