Medicine after failing gcse science

Hi I’ve just finished GCSEs and achieved brilliant results nearly all 7s apart from science where I achieved a 4/3. I have had extreme mitigating circumstances (not talking about covid) leading me to miss 3-4 years of secondary school non consecutively so hence I have a massive gap in my education but I am very lucky to be quite naturally academic receiving all my results without revision for any so the others were quite easy to grasp but with science it’s so content specific so you do need to learn it which is why it was my only low grade as due to my mitigating circumstances I was never able to learn it although science Was always being my strong suit it was impossible for me to achieve a high grade. So I’m really keen on going on to medicine and hopefully be either a palliative care doctor or a psychiatrist and I was wondering what can I actually do! I’m unable to take science a levels because of my results so I’m about to take psychology English literature and music for a levels but medicine is honestly my dream career I have had lots of work experience and am a quick learner so found it easy to grasp and I completely understand that medical school is extremely tough and complex however it is really what I want to do so please could someone tell me what options I have to be able to go to medical school? Really appreciate any suggestions as it’s really difficult and i don’t know how to get to medical school!
