I've recently had a horrid viva. My PhD was referred with major corrections to be completed in 4-12 months. I anticipate that I will have to pay more fees (which the Uni has now doubled across the board).

Any advice on whether I should/ how I should attempt to complete this PhD successfully would be much appreciated.

The story:
1. Awarded 3 year funding to do PhD. Proposal was do a statistical, methods based Phd with applications to social science research (health). (My academic training is in statistics and had worked for several years as statistician/researcher)
2. First two years of PhD, relatively ok. Main supervisor (statistician) dropped me - no reason, but 2nd supervisor took over (not a statistician or sociologist). Submitted regular reports for Board review with outlines, progress, plans. Even got a letter from Board to confirm all was ok.
3. Beginning of third year, my second supervisor (and Director) told me to drop the methods and do a research (sociological) PhD.
4. Somehow completed thesis after one more year of funding as full-time student and one year doing evenings etc as a statistician in research (current job) (PhD subject broadly sociology of health). I immersed myself in sociology - books, seminars, papers, as much as could physically bear.
5. Examiners were sociologists. In the viva had prepared some story about how thesis came about as had previoulsy been told not to mention the change of direction in the PhD. But was grilled on this issue in vivia and found it very uncomfortable to maintain the white lies. However, main stumbling blocks for not passing I think were sociological issues.
6. Current supervisor has been supportive but suggested seeking advice of sociologists at Uni or within Uni associated with my workplace (in another part of the UK).

Now I'm concerned that even if I get to grips with the sociological aspects and/or find someone to advise, I can still be referred again or worse failed when I re-submit. And how can I ask another academic not in the same dept or even the same University to help me out?
(And I'm angry about the fees...... ).

My partner has also dispaired at the thought of 'losing' me again for another year to "silly sociological books".
While the applications of the phd helped me to get my current job, the contract isn't based on my getting a Phd (though obviously it would help generally).

Aside from burnout, I completely stumped as to how I can make this work now.
