I'm a first semester student trying to study for exams. I just feel like giving up because there is so much information to know. It doesnt seem humanely possible. I feel like I have forgotten a lot of what I knew the day before. And now.. I am in the worst mood ever, the lowest of lows. What should I do because I just feel like I have nothing left? Should I still attempt to pull myself out of it even though I doubt it will be successful?
