I am happy to read that a student publishes that their life is hard because too many ignorant people bellow out that college is easy and what not - it isn't.
My student life was nothing but continuous, strenuous effort to pass courses and to improve my study method. All of my years spent at university were fully dedicated to studying and I only went out to a party or two in freshman year.. after that it was hardcore dedication - and it paid off.
Like you, I also had many moments of problems that seemed endless.. for example, trying to pass courses that just didn't sit with me (Statistics 101, Accounting,..) but I had to get all the help I could and I finally made it.
It's also safe to say that the majority - if not all of the students who focus on fun and entertainment, parties and what not are the ones that disappear after freshman year. This very problem happened at my university: 65% of students dropped out after the first year.. and it were the same 65% who went to fraternities and boozed themselves all the time.
Keep going, keep going, do your hardest best to make it.. and you'll make it. Take it from someone who - according to the uni statistics board - had a 0.5% chance of graduating, had professors mock him but graduated with honors anyway.
