In serious need of advice / your success stories

Hi, I’m hoping someone here will be able to advise me on a possible route into medicine for someone in my situation. Please, please be kind as I am already feeling very anxious about the situation I’m in - I understand some people may think I should forget about it but I am 100% sure there isn’t any other career I want to go into.

Some info: I’m 22, My GCSES are all 9-7s (A**-As), during my first round of a levels due to some severe mental health issues I could only get CDE. I was initially predicted I think A*AA. I took a year out and worked full time but severely underestimated how much time I needed for revision and this is extremely embarrassing but I failed again in my resits. I’m now studying a biomed course at a low rank ex-polytechnic university (1st yr). The reason why I decided to start uni was because I didn’t want to waste anymore time and wanted to start building a foundation for my future, if medicine doesn’t work out in the end I would like to work in this field instead. I know everyone advises against doing another undergrad and gunning for GEM but I felt like I had no other options and didn’t want life to keep happening to me.

Has anyone here gone from a low rank uni with bad science a levels into medicine and if so where? I’ve heard of an Access to HE diploma but I know only some unis would consider it and I’ve heard only if your a levels were not bio/chem a levels. Should I retake my a levels again during this year of uni? Should I do the access course? Would I have to do a masters in some other kind of science like neuroscience at a higher ranked uni for my eventual application to medicine to be seriously considered?

If my CDE grade was in 2022 and I failed at resits in 2023 but by the time I apply to grad entry med for the first time during third year it would be 2027, would my a levels have “expired” by then? So only my degree would be considered?

I’m in a much better place now mentally and have better coping methods and recognise why I failed before. I just desperately want to move on with my life and make some progress but I am feeling very stuck.

Sorry this was so long, I’m just not sure where else to seek advice from. I appreciate any advice you guys can offer. Thank you so much.
