Help me go back to school!

Hi there, my name is Gemma Kent-Brown and I am a 20 year old woman who has a dream of being a psychologist one day and working with children as there are many children who deal with horrible situations at home and they feel to scared to tell anybody. I want to be that safe space where children feel they can express them selves. I haven't had the easiest life as I haven't had 2 stable parents who have been able to support me. My mom wasn't in my life much when I was a child and neither was my dad so my gran and aunt have taken care of me for most of my childhood and together with my other grandad and stepmom were the reason i was able to finish my matric in 2018 with 5 distinctions. My dad has never contributed much in my life and neither has my mom which has left it up to my aunt and grandmother who is now 72 to support me. However, 2 years ago today my grandfather tragically died leaving the family with no insurance, policies or savings to speak of. It got so bad over the last year we had to rely on food donations and selling furniture and whatever else we could just so that we could eat and pay basic bills so that really messed with my first year of university as we had no money to pay for it. My grandfather stated in his will that R153000 would be left to my education but as the property market in South Africa is so bad at the moment my gran hasn't been able to sell her house yet. I am unable to register for my second year of university until R14000 is paid to the school varsity college which starts in 2 weeks and it is stressing me out as my gran nor my aunt don't have any money to pay for it. I got 4 distinctions out of 5 subjects in my first year and I really dont want to have to give up my dream of being a psychologist one day. Please will somebody help me.. I have nobody else to turn to and I don't have parents who have money to help me or contribute towards me at all...
