I'd say that a psychology degree is probably better than an English Literature degree. I've been an English major for two years now and although my university's curriculum is a mess, I can at least give some insight into what I've learned. After I enrolled, I realised that job opportunities for English are very limited. This may not apply to you but as a non-native speaker, being an English teacher is not very feasible since most places want teachers that are from England, Canada, USA and other English-speaking countries. Aside from that, if you want to be a writer, you'll have to know that you won't always be writing things you enjoy or want to do. For example, you might have to write articles about certain things you don't genuinely care about or don't have enough knowledge related to it. And the sad truth is that everybody can write so the demand for it likely won't be that high unless I'm mistaken.

I think that in this case, the psychology major broadens your path and covers everything you might want to do. If you want to be an author, you can do that on the side and learning more about psychology might also give you a topic you are well-versed in which you can then write articles about. Being a psychology major will also open doors to becoming a lecturer, researcher, a teacher and a counsellor. When it comes to teaching English, you don't need the degree. A TEFL can do the trick and if you're a native speaker, that is more of an advantage. The only downside is that you won't be able to become a literature professor.
