I hate hearing that you’re in this situation. I know there are a lot of things that make it hard to escape but I hope one day you’re able to. I don’t know if you’re in the US but just in case: thehotline.org leads to the national domestic violence hotline’s website, which has an easy X button to press if you have to close it quickly. The website says they can help in cases of emotional abuse and when people are stuck due to finances.
I really wish you the best OP <3
I’d guess books are different, but researchers don’t get paid anything for publishing in academic journals
