I meet with my PhD advisor quite irregularly so we arrange meetings on an ad-hoc basis depending on work progress, availability etc. Usually we communicate a bunch by email about the state of work.
I'm want to leave my course. I don't see how any minor changes to my work would change this decision. At this point I mostly just want to have a couple weeks of mental health break with no pressure to put time into the PhD, so I can have some brain-space to clear the remaining doubts from my head.
Should I let my advisor know that the meeting we are scheduling for later this week is about my position in the programme instead of normal project progress report?
PS. I am aware that a natural way to frame this would be to mention in an email that there I have some doubts about my work that I'd like to discuss. However that would be misleading - I'm pretty set on the idea that doing this degree is not right for me and the only doubts I have are whether this is the right decision at this time. I'm not interested in being convinced I should stay and try to "work things out" because my decision to leave is related less to problems I have with the course and more to simply having no reason why I should want to be doing it in the first place.
