@sarah1994,
Learn how to write, particularly how to blog, and work from home through Upwork. Lots and lots of sites need content writers pretty desperately. Cultivate a reputation of speed, accuracy, scholarship, and honesty.
It will help you get more work and you'll get paid far better if you get a BA. As I'm sure you know, there are a lot of places where you can get a BA online. You can try one of the schools I went to, Quinnipiac. I thought their courses were excellent and they prepared me really well.
