I persevered in trying to like my PhD for two years. I have just suspended but will not be going back to it but instead will reapply to do part-time subject with different supervisor who is the best in that field. The last year has made me ill with stress and depression and my relationship with my supervisor has always been awful (my respect for said second-rate super is now non-existent). I have had a successful previous career and I want to feel like that person again, not the under-confident gibbering wreck that all the toxicity has turned me into. if any of this resonates, don't wait as long as I did!
All the best and good luck.
