Hi Naomi,
Your message is somewhat vague too :-) I'm not sure what the timescales are, how long it's been since you applied. Unsuccessful candidates are not always notified immediately and sometimes not at all.
The process of PhD recruitment is different in every university and it depends a lot on funding situations, number of applicants, and the amount of workloads in the environment. Covid-19 has caused a lot of disruption to universities and many are in the process of having to change their entire teaching strategy once again for the new semester. Many are increasingly understaffed, some departments have lost staff members or are under a recruitment freeze. PhD recruitment is complex even in normal years. Academia can be chaotic and ever-changing even in normal years. This is not a normal year.
I'd say that if you are already stressed out by ambiguity at this stage, then a career in academia may not be right for you...
