Thanks for the advice. I already get support for my stress and anxiety and I can't sustain anymore this situation. Please could give me information if it is possible that a supervisor could launch a lawsuit against a PhD student in case he quit given that they had written agreements in finishing the thesis?

Dear all,
I am writing up the PhD thesis : I have written the chapters of introduction, methods, results and a draft of discussion; examiner for the PhD viva have been appointed and we are in the process to decide a date for the viva. However I feel so exhausted, stressed, anxious and negative that I don't want to proceed anymore. Especially for the discussion I feel most of the time blocked and to overcome my anxiety I need to take commitments that distance me from the thesis. I am concerned about the time taken by my supervisor to correct the thesis and the amount of corrections that could induce me in a more stressful period. Moreover I feel that I will passively engage the viva not having any interest in it.
I am not suitable for the PhD and I don't want to force anymore my self to do things I don't want and simply the PhD does not belong anymore to my life's project.

My thoughts concerning quitting from the PhD program go on since more than one year and I have been proceeding until now in a passive way.
I realized that what blocks me in taking a decision is the reaction by my supervisor: I am scared.
I was wondering if my supervisor can use a legal action against me in case I quit given that we have written agreements in finishing the thesis: I wrote a plan for the writing and there is an email in which I guarantee that I would have finished the thesis. I am tryng to do so but the continued study is negatively affecting my mental health.

Thanks
