Student needing funding for historical debt to register for masters research in nyaope addiction

I’m a scientist and student currently trying to register for my masters. I currently do not have the funds to pay off my fees from my honours last year. Due to family financial issues have been unable to register.
My mother is the only person who has an income in the household and has a substantial amount of debts to pay off as well as maintain the household. She cannot afford my fees especially with the high interest added by my university.
My research for my masters will be on nyoape/heroin addiction which is a field with very little research. The research I am doing will be investigating the effect of drug use on expression of genes and linking this to the phenotypes (physical effects) of the gene expression observed.
This research will aid in understanding drug addiction and how it interacts with DNA to cause long term changes, as well as assist in development of treatments for drug addiction. Drug addiction affects a large amount of the population in south africa, with these individuals not being able to obtain help for their addiction.
Without being able to register, this funded research will not be able to continue. I ask for your help so that i can help my community and enhance the scientific knowledge regarding nyaope addiction.
