Those are not good enough for medicine. Even if there were difficult circumstances, you have not yet proven yourself capable.
Retaking the year is generally a deal-breaker for most med schools though if you did want to contact them with regards to your specific circumstance you could.
Your other options are:
1) Find out what went wrong, fix it, and work like you've never worked before this year. Then once you have your results, you can apply for medicine next year. You'll need to get at least AAA overall to stand a chance.
2) Look into foundation courses. These have various requirements that you will have to look into and/or contact them to see if you are eligible.
3) Do another degree, get a good outcome and apply for graduate entry. This is longer, more expensive (though loans are provided) and more competitive.
4) Lastly, and I think you need to spend the next few weeks giving this some serious thought, consider whether medicine is for you. Why do you like it? What was it from your work experience that you enjoyed? And then seriously look to see if these factors can be fulfilled elsewhere, be it in the large variety of allied health professions out there (nursing, physiotherapy, occupational therapy, clinical biochemistry, lots more) or even outside of medicine.
Good luck whatever you decide.
