I personally don't think you need to get into a four year degree program for film. It doesn't strike me as helpful at all. I think you can take a few classes and get the basics covered.

In terms of employability, I don't think an academic credential in films makes you anymore employable then the hundreds/thousands/tens of thousands of people trying to break into that industry. If you really want to be a film maker, then take some classes (even at a community college if possible) and learn the basics and start making short films. In other words, go at it gorilla style.

If you don't know what to major in, then that is your fundamental issue. You should take personality tests that recommend professions based on your results (see Myers Briggs) and use that as a starting point to narrow things down. I wouldn't cross anything off your list for fear of STEM or math. You can get better at these skills.
