Welcome, sugar. That looks like a jade plant, possibly. Whether it is or not, it was not getting enough light. Even moving it to light after it showed signs of being unhappy is enough to shock it even more. I am not sure if that one can be saved. But if you try or get another, you will need to get a full spectrum light in your cubicle to promote growth. Water once a week or less. Every two weeks probably is best.
The full spectrum light would also help cheer you up as well. Good luck!
