We've all heard of postpartum depression, though I'm not a woman so I have no idea what it's really like.
I am wondering if there is any medical/psychological evidence to support similar (reported) feelings after the completion of a big research project.
This is my (I'm the sole author each time) fourth time sending a paper to a journal after spending countless hours working to finalize the draft. This typically involves a frenzy at the end where I work 12 hours a day trying to perfect the paper. This is in addition to the stress incurred while actually creating the research (in my case, mathematics) in the first place.
Each time I finish a paper, including my most recent, I have feelings of emptiness and anxiety. I'm not here for medical advice, I'd just like to know if anyone is aware of some scientific basis for these emotions.
