So basically, I've been in this lab since winter of freshmen year, and was paid $1k to do research work over the summer while also taking summer classes (commuting for 1.5+ hours each way from home every day). I was also given my own project (which is WAY too much work for one person, I was only trained on it because no one else in the lab was willing to give up their winter break for it (~8 hours a day for the entire winter break, same commuting situation + no compensation). Now I'm in my soph year and I asked my PI for a letter of rec for a summer research program that would provide $3k and housing, to which he said "i mean I'll write it but it would be good if you stayed here for this summer".....now I'm feeling super awkward and anxious after the meeting and I feel obligated to stay in this lab, where I've already been in for over a year and it doesn't seem like a paper will get written anytime soon. Does anyone have any advice for moving forward in this situation? I honestly haven't been enjoying the research recently and have been contemplating quitting the lab because I feel like I'm burning out with that + my BME major + pre-med stress.
