I'm in the submission pending (4th) year of a social sciences phd and am really struggling. I have been working as an associate lecturer since September, before that I had funding. I am absolutely exhausted from trying to fit everything in (single parent, 3 teenagers) and today broke down in tears in supervision. My supervisors were very understanding and suggested I take a couple of weeks off the phd completely, but I just don't think a couple of weeks will make much difference and I dread the thought of it all piling up until the summer months ( I have to submit by September).
I am not convinced I want to work in academia anyway (even if I could get a job) so perhaps it would make more sense to just give up now?
