Yes.
Mental health-wise, on the cost of living, for me personally, when I did not have a significant other to depend on for finances, it was a little more of a struggle to make sure that my budgeting for the month or a semester was very well done. I'd think, “Okay, this amount is going to rent and this is going to food, and how much is left over for things I can do that I enjoy, that will help make me happy?” Those were things like going out with friends, or even simple things like a subscription to music or anything like that, anything that would direct my attention away from studying—when we're not studying, like in the evenings—and to things that would positively affect our mental health.
