So sorry to hear about this, it sounds devastating. I am suffering too mentally and I am just 6 weeks into my PhD, regretting joining and moving to this far remote location for the role.. I am tempted to quit but I never quit. But then again, no previous job has made me break down into tears as much as this one and its just been 6 weeks. I am doing a research assistant role with a part-time PhD attached to it but expected to finish it in 3 years. I am working on a topic that I have no experience on and my supervisor has a "philosophical" way of supporting me; "learn yourself". For the first 4 weeks he would not even meet me, stood me up on the first 3 meetings, said how he hates meetings and how I should just ask other PhD students for support as he is too busy. I don't know why I am typing this here, but reading through your post and the replies made me feel as cliche' it sounds "seen". I was not ever passionate about this topic but I got enticed with the better salary package as its a research assistant role attached with a part-time PhD. I am doubting all together if I want to work in academia entirely now but that would mean taking a paycut, disappointing my family (partner and newborn, wider family).
