Let's say that I was given unacceptable conditions for returning from medical leave; basically I had to self-fund at least the following year of a physics PhD. Knowing that doing so would result in a financial disaster, I am definitely withdrawing from the program that I spent just one semester in, doing no research whatsoever, with the understanding that, if I still wanted to earn a PhD at some point, I would have to transfer.
I could always mention, in an addendum (if there is space for one), medical problems, going to medical services, such as a physician (on-campus and later off-campus) on a regular basis for 75% of the only semester I ended up attending, and leaving school to take better care of myself. (I feel I did what was right from a medical standpoint) But when there is no space for an addendum in an application, I was advised to just drop a line about "personal problems" or "extenuating circumstances" and, now that these issues are resolved, I am excited to do research again.
And also, I have two publications on file by now (one in PRD and another in JMP), whereas I had none when I applied to PhD programs the first time around (2015 cycle). Because I do not feel my GRE scores were an issue, I do not feel the need to re-take the GRE, general or physics, since they are still valid. But TOEFL, on the other hand, I would have to retake because the scores are no longer valid.
P.S.: I never had Ws before that particular semester, but still somehow ended up with 3.80 for what coursework I still managed to complete. If you need more information about my file or anything else, please, let me know.
How will an early departure from a PhD program (in its early stages) due to medical reasons affect future PhD applications?
