I've sometimes struggled with depression, which is quite common for grad students. I applied to grad schools with my fiancée, and we were married for basically the entirety of grad school. When she graduated, she moved away for a new job. My depression deepened, and I used video games to cope, which was not effective. Failing to properly address my depression interfered with my research, and brought about the end of my relationship. I’m pretty extroverted most of the time, and when I spent time leaning on video games, it was very isolating.
