hey i'm super stressed about english too, i'm currently doing about 1hr for english lit and 1hr for english lang everyday because it's the easter holidays but when we go back to school i'll probably do just 1hr for either one everyday and alternate them. english is my worst subject so it's the one i revise most, don't know what it's like for u in comparison to ur other subjects but if like me u struggle with it definitely spend more time on it.
for english language i mostly watch youtube videos on how to answer each of the questions and follow the assessment objectives/mark schemes, then do lots of past papers/questions. idk what it's like for edexcel as i do aqa, but if it's similar the aqa timings are super tight so definitely recommend doing these in the time u have in the exam.
for english lit, to revise content i mostly use the cgp text guides, seneca and sometimes physics and maths tutor, and then i've made flashcards on things like themes, characters, quotes, plot summary etc. however given it's only a month now u probably don't have time to make loads of flashcards, so to revise the content ur probably just better off using something like youtube videos or seneca (or maybe just reading thru the cgp guides if u have them and making very brief notes/mindmaps etc at most) as they'll help u get thru the content faster. also again i reccommend u do lots of past questions.
i've attached below some of the resources i use but for ur exam board if it helps:

https://www.physicsandmathstutor.com/past-papers/gcse-english-literature/my absolute favourite resouce is Mr Salles on youtube, his videos are so good and have been really helpful for me. however i don't think he does any videos for edexcel language sorry, but i don't think the literature ones are exam board specific as we all do the same texts and the assessment objective are almost identical so they could be helpful?
https://www.youtube.com/@MrSallesTeachesEnglish/featuredi hope some of that helps, sorry if it doesn't as again i do aqa so it might be different, but doing past papers and understanding how to answer each question according to the mark scheme/assessment objectives will defintely help. best of luck i'm sure it will all turn out fine for u in the end
