Finishing vet school

I'm a 4th year vet student in South Africa supporting myself. I only have a few years left of my studies and fees as well as books get very expensive. up till this point I was juggling two jobs with my studies, but the one place where I worked got closed down. I only have one job left and am trying to make it through to final year.

I really am trying, but it is a lot harder than it sounds. I would genuinely appreciate the help and it will push me further to my biggest dream ever, to be a veterinarian. I am an underdog who's trying to make it in the big world, my main goal is to make a difference in the lives of animals in need.
