Did you apply to apply to a University and get rejected? Have you researched any foundation courses that can lead you onto your chosen subject? You can apply to these through clearing, and you can find courses offering places on whatuni. At this point, it can be possible if you sell yourself, state the circumstances which led you to not do as well as planned and many universities will sympathise, largely those whom are not as prestigious but can still lead you to the career you want. I believe Plymouth University has many courses that may appeal to you and they accept people who do not meet the required grades! Don't give up, you can still get there!
