Am I a writer?

I consider myself a writer simply because that is one of the subjects I enjoy the most. What I don't like is when we are assigned a subject and aren't aloud to write what we think(for the most part). I believe that someones thoughts should always be written because that is what helps them express their emotions. It can be difficult to write ones emotions because not everyone thinks the same way you do and they can't read it with the emotion you wrote it. Sometimes I write more than I should because I let all my emotions out but I think that is what makes me a writer. Regardless of what my style of writing is I want to improve my skills by taking courses, especially now that I'll be starting college in  the Fall.
