Dude calm down, don't get stressed out. If you want to do film go for it, I want to pursue Photography although it has no use as a real career, by that I mean like a good paying job. Also just get a minor in something that will help you get a job, meanwhile you find a job in your skills on film.
I never got my high school diploma the way you are doing it, so I don't know those stressful things you are going through. If you are stressing out on your classes drop one or two. Depending on your situation. But just remember you should satisfy yourself in your career, if you want to be a film major go for it. And just get a minor in some good career. Hope that was helpful.
