It's so sad to hear about your story, but I would advice you to think about all these critically. This visa officers are now examining applicants thoroughly, they want you to be well established in your home country. And how to achieve this is by having verifiable job that pays you income, attach properties that you own by yourself or a gifted property from parent.
Know fully well that, getting a scholarship is just to sort a single part of the Visa processing category - the financial. However, there are many others.
Also, since you are going for a course that is different from your first degree, you must show cogent reason why this move is a progression in high ranking to your initial qualifications. To show this, have a work experience in the field, have a volunteer experience in the field, show cogent factors that motivates you to choose the course, show how the course will be instrumental to your future goals and ensure you coined everything back to your home country once you are done studying.
I will advice you to examine their rejection critically, and if you want the approval really much, give to them, what they want from you.
Goodluck.
