Want to study medicine

I am 24 years old and I always wanted to study medicine, but i cant afford it, my parents cant afford to send me abroad to study either. Medicine is all i ever wish to do, i have a degree, and im doing my honours degree in biological science, however, medicine is my true calling, and the purpose of my life.
The reason i cant study in my country is because they work on a quota system, and since i am not a certain race, my chances of getting into medical school is very slim.
I have been trying to give up my calling, my purpose for years now, due to finances, however, i cannot phase my calling, and i now seek help from anyone willing to assist me.
I just want to leave a mark and help people and make a difference to their health, giving everyone the best possible quality and service...For when i depart from this life, i want to have make a mark in this lifetime, through medicinecvcvvvvvvvvvvvvvvvvvvvvvv
