This is a question that ultimately only you will know the answer to, but you can ask some others to give you information. First, I’d ask scientific researchers you know, or a professor, how they feel about reading scientific papers and if you lack of interest resonates with them. Then, I would recommend finding out if there are tips to reading. Maybe the not understanding the papers is making you not interested and some reading tips from those professors (or some librarians – they are at the reference desk and love to talk about this sort of thing!) might help. Then you will have more information to decide what you want to do, and what you are passionate about.
