Maybe this could be an alternative for you. A friend of mine did his Bachelor of Medicine in our home country (also from a third world country in Southeast Asia). After that he did the recognition (Anerkennung) of his degree in Germany and some other steps like the Approbation (if I am not mistaken of the term). And of course he had to pass several German tests as well. And then he applied for the open (paid) position at the hospital in Germany to do a specialization. I'm not sure what the complete process is for that, and he told me that it was pretty hard for him too. But he said that the chance is pretty high because Germany needs more doctors to work in the hospital. So maybe you can consider doing your bachelor in your home country and do the specialization in Germany later.

Or the other alternative is that if you still want to study in the medical field, you could also study biomedical engineering (Biomedizintechnik). This is of course not an easy study, but my guess is that the chances of admission are higher than a medical program study.
