My Future

Hi
My name is Kyle and I'm asking for help with my future. I've been working since I was 16 so I could support my mom and baby brother, my mom unfortunately lost her job at that time and we had to live in a shack in a back yard to survive, luckily the nearby DVD rental store was looking for employees and they hired me and after three years there my mom got a job offer on the south coast in Margate and so we left for a glimpse at a better future, but unfortunately four months after we arrived the company where my mom was employed was sold off and she was retrenched. Luckily I had found work and have been keeping the family above the absolutely destitute line since then. My families motto is "Just keep swimming" no matter what we didn't give up and we where okay for a while but i have now been let go from my job thanks to the covid situation and now we are looking at the end of what I had saved up. Since I was a small kid I've been in love with sci-fi movies and gaming and have always wanted to bring my own imagination to life and have decided to pursue a career in 3d rendering but unfortunately I lack the funds for the courses and a adequate computer, the computer I have is a Pentium duo core- 2gb ram- HP compaq, which is 10 years old. Please help me make a future for myself.
Thank You for all your help
Regards
K
