It was likely a combination of several things. I had moved to a new country after high school for college. The college also happened to be in an extremely cold part of the country, and I joined in the winter semester. Culture shock, being alone in a new country, seasonal affective disorder (I come from a warm tropical country), being in a long distance relationship - they all likely contributed. I also made some pretty bad career moves immediately afterwards, which likely didn’t help.
