Studying BTEC IT, want to become a writer

So basically what the title says, I'm pursuing a L3 extended diploma in BTEC IT & Computing, achieved a Distinction in my first year, but I don't want to go into IT and would love to become a writer, which is my newfound passion.
Do I need an English/Humanities related degree, or would it help? I have thought about the possibility of studying Business Management after college since my course has quite a few business modules, and from there trying to get a postgraduate degree related to writing, but I'm not sure how transferable this is.
Additionally, are there any platforms you recommend I upload my work to? Have had a look at Medium but wanted to see what everyone else recommended. I like to write fiction from stories and poetry to sometimes non-fiction i.e. technical writing about Computer Science and technology or self-help guides (involves a little bit biology with Psychology and sports science for the exercise aspects.)
I really want to write fiction books and poetry, and possibly a non fiction self help book since self improvement is something I am really interested in.
Would love to hear thoughts from people, thanks 🫡

So fire round questions:
Do I need an English/Humanities related degree, or would it help?
Nope. You need no qualification to write, but you need a good writing ability. Shakespeare for example never attended university (not that his writing is any good).

You can do business degrees with qualifications in any subject. A better question is why if you don't want to go into academia studying business. It's not really an accredited subject or required for any job role in industry. If you have such a degree, employers would just see you as another graduate with an irrelevant degree, even if you apply for business related roles (and pretty much anyone is eligible for them irrespective of their qualifications).
from there trying to get a postgraduate degree related to writing, but I'm not sure how transferable this is.
In terms of skills and relevance, none whatsoever. You can still do MA in creative writing with undergrads in anything. It won't exactly help you to secure jobs in writing though (in my opinion).
are there any platforms you recommend I upload my work to?
There are plenty of writing clubs on Facebook and Meetup that you can look for. If you are looking to publish short stories, a quick google search provides the following results:

Go for it. I think writing fiction and poetry is a lot more difficult. I would try to study under a mentor (really good writer with a long track record) more than I would do a degree (but a writing course covering the basics is recommended).
Pretty much anyone can become a self improvement writer, the question is whether the book you are writing will sell. The second question I would ask does it actually help. The third, is it any good.

Wow, thanks so much for the advice, i think what I am going to do is study Computer Science at Uni and secure a job/stable income, alongside practising writing at my leisure. I was honestly so stressed about not studying English or History etc at A-Level but your comment erased those worries. Thank you 💪🏽

Whilst I am not against people doing CS at uni, what specific role are you going for?

I wanted to do Computational Neuroscience research and use my findings to help the study of self improvement, promoting brain health and stuff, but ofc I can't go through that route if I want to become a writer. Honestly not a clue, but I am interested in robotic software engineering and the work of AI

Perfectly good reason to study CS at uni then.

There's no rule to say that you can't do both. Ofc being a writer and working in research are both extremely time consuming, but at the same there's nothing to say that you can't do both at the same time.
I know of an economics lecturer who wrote fantasy books in his spare time.

I would probably sit here arguing that you don't need a degree to go into software engineering or work in AI, but people will say different. A degree in CS won't hurt your chances.
If it's specifically computational neuroscience research, then you would need a CS degree (or something akin to neuroscience). The key thing is probably to do the MSc in computational neuroscience before going onto the PhD, but I think you might be able to get away with skipping the MSc and going straight to the PhD if you picked all the relevant modules in your CS degree and you are lucky enough to find a PhD course that allows you to specialise in computational neuroscience. Don't quote me on that though; you should do your own research in the area and ask a lot of questions with researchers in the field.

Yeah that's the plan, to do MSc Computational Neuroscience after my Computer Science, I could take up the research and writing alongside as a hobby, they would be two things I love the most. Besides, I could combine the two and write books about my research too

Sounds good. Give me the titles of your books once you have written them.
