Should I stay or should I go?

When my adviser asked to speak with me in her office in March, I figured she wanted to discuss plans for a possible lab shutdown. What she actually said took me completely by surprise: She was moving her lab to a new institution. I could go with her, uprooting my life but continuing to work on the science I loved-or I could stay, find a new mentor, and hope to keep some semblance of my original project. "Either way, you will get a Ph.D.," she reassured me. She emphasized that she would do everything she could to support me, no matter what my decision was. Still, there I was, two-and-a-half years into my Ph.D., with a huge curveball to deal with. When I had heard about other students in similar situations in the past, I had always thought, "I'm so glad that's not me." Now, it was me.
