Sticky situation- what to do? URGENT

Hi everyone,
so basically when i was in year 12 i didnt get the grades i wanted to get for Stem so i had no choice but to enrol in my current school (i’ve been here like from the beginning) and had to chose random subjects such as sociology, history and english lit. I knew i didn’t want to do this but i have i gave it a go for a year, i always thought my school would accept year 12 retakes however they didn’t even though they wrote it down as a option of mine, but anyways i decided to retake my gcse for science however i didn’t plan on that after a few months as i changed my plan to stick with my subjects and do law. Moving on I reached end of year 12 summer mocks and got a U for my english lit test which was a huge disappointment and shock as i thought i did well, my HOY spoke to me and the head of sixthform about my english grade and how i was constantly at a D or below and this time i even got a U for my end of year 12 mock. So they decided to give me until september for assessment which i didn’t do as well, i only wrote my thesis and one paragraph. I have gave this alot of thought and consideration but i’ve been through a lot of personal and family issues, i got a 8/7 for gcse english but now a U for year 12, anyways i’m in the beginning of year 13 and i have a few options because i despise english (no offense to those taking it) but it’s just really not for me, tbh i didn’t even want to do it in the first place, i’ve been giving it a try but i just keep struggling and that’s why i can’t bring myself to revise for it either since it’s not something i want to do at all.
my options are:
find a sixth form or college which i have and all of them either say they don’t accept year 12 retake or are full, i have found some which do accept retaking sixth form as i’m in year 13 but it’s a bit far (it’s in london and i live in uxbridge so idk)
next option is to drop english lit and carry on with 2 a levels which are history and sociology and take a gap year to do business A level or Econ (it was full before but i originally wanted to do that)
my end result of my outcome is that i want to go uni and do either something related with finance or marketing because RG unis require Lnat and that’s why i don’t want to do it but yeah i like business and marketing but i’m so unsure like genuinely my head is spinning with thoughts and my mental health isn’t the best either. Please give me genuine advice!! also i have spoken to my teacher about this but i’m still unsure about what the rest of them would say, i just want a new start so if any of you have any suggestions or sixth forms around Harrow or hayes/uxbridge please let me know!! MANY THANKSS

You could stick with 2 A levels and look into a Foundation year?

Thank you for replying! I’ve been trying to find a lot of schools like emailing and calling but so far I haven’t a really found any that are good or accept year 12 retakes, if you know nay around West London in Hayes, southall, slough and Uxbridge please let me know. I have been researching for foundation years but most of them need 120 UCAS tariff points so idk what to do, idk if i can do a epq or something
