I am an undergraduate in theoretical chemistry, and I am currently having a summer research internship at one of the top institutions in the world. I was dreaming about this experience for a long time, but now I think that I can't handle it.
I started to feel drained of energy six months ago when my family had serious problems in their relationships, finances and health. Now, it's two weeks into my 8-week-long internship and I am unable to focus on anything at all. The only hope I have is that intermittently I have bursts of energy, when the idea of leaving seems preposterous, but they only last 1-2 days max. I also have troubles sleeping.
I have always been a diligent student coming in top 1-5 in all examinations I sat. My internship last year also went quite well and my results from it resulted in a publication. I have never felt as I do now, and even though I'm trying really hard to pull myself together, I'm failing.
I wonder how much quitting would affect my reputation, especially if I'm being honest that the issue is about my mental health. On the other hand, if I stay but am utterly unproductive, would it be worse?
