@AnamethatstartswithEI have had the privilege of supervising several PhD students and I transitioned during the supervision of my last three.
Firstly - congratulations Honey. Doing a PhD is a pretty awesome achievement and doing one when you are transitioning deserves a pretty massive hug. Big Hug.
It is perfectly normal that during a PhD that the student feels like - giving up. Changing direction. Taking up high risk sports such as BASE jumping, taking up a musical instrument (Tuba), drinking, smoking dope, completing their friends PhD, finishing off various Hons Projects, not writing papers, not writing grants, ignoring the supervisor, being pretty damn sure that the supervisor's PhD was on such a simple project that they never needed to study - in fact just about anything but doing their PhD (Some of the comments are flippant).
I would caution, as I did with my students to just take it easy. Continue, maybe take a break, maybe take up meditation, maybe help me supervise a student, maybe help me with some teaching, maybe come around on a Saturday afternoon or morning or whatever and help me with some gardening or maybe take a bush walk.
The key always was to allow you - the student to clear the mind, help distract from the whole thing and realise that there is fun and stuff and... stuff.
I would really caution against stopping and giving up for a new direction - just at the moment. I would suggest finishing this direction first.
Oh and I started my PhD when I was 36 and received it at 40. I wanted to give up from day 2.
