As for the above comment, "dropping out will look seriously bad on a CV" sounds so sad. I suppose our lives are suppose to be about looking good on a CV? Although, I do think sticking it out and then looking for other things might be good, I don't think you should have to stay just because it might "look bad."
Try to at least just finish the year but looking for something else that you'd like... Anything really. I'm an economics student and I got into coding that I do on my own time which has been a savior! I hate economics but I'll stick it out, work on front end and a bit back end while in school then pick it up for real this summer once I'm done.
If you feel too down, then drop out, people do it all the time. You do need a change of some kind.
Nevertheless, it will be nice to finish. But, life shouldn't be this hard. Your happiness is your responsibility though so if you are not happy you need to figure it out as no one else will do it for you. Don't listen to people who say stuff like "oh you hate your life? Oh well, at least make sure it won't show up on your CV."
Good luck. Remember there are a lot of us that feel the same so try to do the best you can and don't be too hard on yourself!
