Very inspiring! There's a saying in the US, "what if the cure to cancer is in the mind of someone who can't afford an education". I was on my own young, like you and was faced with the prospect of trying to make ends meet while in school, it isn't easy.
I noted you're new on steemit. There's a great markdown guide in the getting started section. It has the ways to add headings, which will make your posts easier to read.
Congratulations on everything!
