I lurk this sub-forum fairly regularly because I, too, wanted a PhD in English Lit before going into another field. With that being said, I feel like if you have to ask strangers on the internet about what you should do, it seems clear to me as an outsider that this isn't the right choice for you. I share that with the caveat that I don't know you and you can do whatever you'd like with your life and time; and ultimately, none of us can make that decision for you. However, you seem to have a history of posting here and waffling back and forth about getting a PhD or which sort of program you should be attending, etc.. Perhaps releasing this and moving on in another direction, one you clearly state you'd be happy in, is what's best for you. But again, we're just all strangers on the internet.
