I have gone years without writing before. So I kind of get where you're coming from. Hang in there. Think of your goals. What kind of job do you want to get once you graduate? Pretend like you already have that job and write articles that are related to it.
I know you said you wished you could just be a student and not have to work, but I feel like if you can work in the field while you're in school, you set yourself up for success on multiple fronts. First, school will become more effective as you'll be able to relate concepts you learn to your actual experience with the agency. Second, when you graduate, you'll have relevant experience in your field which will set you apart from your student peers.
