Some help for trimming down your word count :)
My role model, who will forever be my father, died from cancer when I was only 12 years old.
My father, my role model forever, died from cancer when I was only twelve years old. ...2 words saved :D
At a time when I need my father the most, I have taken as many steps as possible to further myself, education-wise and in the real world.
I don't understand why included the first part :( Did you mean that when you needed your father's support the most, he's dead and gone? If that is so, you need to improve this line.
What is the prompt? It's difficult to provide you a more meaningful feedback without knowing it.
