It is very important to follow your area of interest. Fiction writing and psychology can be followed even now no matter a person is from commerce stream. Go ahead by doing graduation and post graduation in psychology from a renowned university. You can even think of doing a doctorate in it if you are really interested in it.

You can get the list of subject from above link. Also, I think Mumbai University gave same subjects for it's all campuses because they are recognized by Mumbai University.
the scope of language course is growing day by day in India due to its international relations to other countries so you may get very reputated job in ambessiss or MNC as a translator or work as a language teacher in any reliable school/institute. Also, you can go for further masters in the language to gain more efficiency.
Hope this helps.
