I recently terminated my PhD - a very hard decision after 4 years of study. But my mental health hit rock bottom, after it had continually declined so much over the years. Worst of all, when I seeked help from my universities student wellbeing services, I was told to 'google my issues'.
What were the reasons? Research results not turning out well? Not enough supervision or too much micromanagement? Too much irrelevant tasks? Stress about funding sources?
