Battling Depression as a College Student

Life in the university is not the same as what I am imagined or what I was told in senior high school.And the gaps between my major and the subjects which I once did well in seem to be huge.What I am now depressed about is that I lost interests in my major after I got the first expression of what I will study.
When I reached my first goal in university --the CET4, I became quite confused about what I am supposed to do next.Without aims,gradually, I did not care about my major and buried myself into games and animation. And I deal with my academy in a very negative way. So when the results of the first semester of my university turned out, almost every subject just got a pass. However I placed the problems not on me, but on the major.
I should recognize that it's not what I was used to be. I try to persuade my parents to allow me change my major. But my parents rejected my plea, saying that they always care about me and want me to be happy about my future. However, in my senior high school, I dream of the further education of chemistry and biology. I always keep an active attitude towards original things. But the accounting seems boring and plain. Maybe when I grow up older and suffer more, I can realize that I would like to accept it rather than change it and finally realize that this difficulty is just the piece of cake.
