Graduate school can be tough, which is why you can't do it alone. It's important to build professional relationships with fellow graduate students, faculty members, and (most especially!) your advisor. But this isn't always easy to do.
What do you do if you don't "click" with your cohort? How do you work with an advisor who seems distracted or difficult to communicate with? What if you've decided on a nonacademic career, but you're unsure if your advisor will be supportive? What do you do if you're experiencing discrimination or harassment?
