I like it when I make new discoveries. I like it whenever I think about my work being published. But these are such rare moments, at least for me, that I wonder if it is really worth it. I have considered being something like a career post-doc, but that too can be miserable. It is not as stressful as being a PI, but just as uncertain. I'm tired of the uncertainty. So as of now, I am losing my passion for being a scientist gradually. That makes me even more depressed. I worry what my peers, friends and family will think. I worry about how happy I will be if I leave science. Most of all, it is going to hurt like hell knowing that I couldn't prove myself. That is the worst part, I think.
