I remember classes on harmony/counterpoint, etc. in my first year at uni, and they were incredibly boring! Two hours on a Wednesday afternoon, during which the class would slowly sink into slumber. But I think it is necessary to understand these elements in order to progress as a composer. There is a huge amount to learn and this is always based on theory. Composition courses at
all levels will incorporate this, and of course analysis of the works of other composers to get a greater understanding of musical structure, form and technique (and at MA level it doesn't let up, but only intensifies!). Composition is a huge subject to study and to make the most of it it's a good idea to do so in a structured way and with the help of not only a competent tutor/teacher, but one who you can get on with! Composers never stop learning, from their own experience and from the work of others.
Composition is a lot of fun, but it becomes even more so and more satisfying as you progress. I don't know to what extent you've studied, but it might be worth looking at the GCSE/A level syllabuses if you haven't done so yet.
Lots of luck and continue to enjoy
