I am in my 2nd year of a neurosceince PhD in europe. The project had a very clear vision even before I had applied. This meant that I came into a project which was well defined and planned with many intersting findings ahead of itself. My previous experience during my master's project was quite challenging as I had a supervisor who was often harsh and critical. So, it was very refreshing to have my current supervisor and post-doc advisors. They are extremetly nice people, and I could not be happier with them.
My first year was very productive where I did many experiments (as planned), and one point my supervisors even joked about me being a "super PhD student". In the begining of my 2nd year however, I hit a big snag. I fell into a deep depression, during which I found no joy in any aspect of my work, not even in basic activities like eating and sleeping. My primary task was to perform computational analysis on certain experiments, but I struggled immensely with it. I genuenly belived that I was incapable of figuring out the coding part of the analysis, or come up with anything new. This went on for 8 months. Eventhough my supervisors were very helful, I did not go to them soon enough becouse I was afraid of being kicked out. I continued doing experiments, but did not come up with any data or results to show people.
Right now, I am in the last 3 months of my 2nd year. I seem to have suddenly gotten my mojo back, and started to read and write again. I have mental strength and energy to bounce back, but my post doc supervisor has mentioned that she is loosing faith in me. The kind of work I do takes time, but because I am not doing statestics correctly, it is making my post-doc worried that she will have to go through the stats after me.
I have done original work on my own before, and that felt different. In those instances, I was able to handle most tasks on my own, although I acknowledge that the difficulty level was very low. But here, I am just following orders to complete a very intereting project. I only introduced one experiment on my own, rest everything is their idea. I feel like my job can be done by a technician. This is again effecting my good spirits, which was very hard to get back. Eventhough I have thought of quitting and ending things so many timmes this year, I have decided not to do so.
Realistically speaking, I cannot do anything "new" in an years time in this feild working with animals. But also dont want to feel like I am getting a degree that is not my own. What should I do here to stay motivated? I am planning to talk to my supervisor, but I dont know what to say so that I don't sound ungrateful. Because, I am very grateful for this oppertunity. Pursuing this line of work has been a lifelong dream, and I'm concerned that I may not be meeting their expectations as a PhD student, which worries me even more about the situation.
PS: One important observation I made - in both good and tough times, I've been consistent in my teaching efforts. I've mentored students and organized science events successfully (from the feedback I got). This makes me wonder if I might be more suited for teaching than research. Even though I enjoy research a lot, the stress associated with it ( especially during challenging times) has me questioning if it's the right path for me. And if its worth it.
