Get some professional work or work experience in the field that you want to do your masters in or in a field that you would like to work in. If you are able to get work this would help pay you as well as give you some credible on the job experience which could help you with a master's later. I did my masters about 8 years later than I planned to because I had the same funding problem as you are having.
Also so if you can apply for a Bursary from a organisation relevant to your masters. That's trying to find out if a hospital or a place related to your line of work will give you a grant to do your masters. You also have the option of taking out a loan that is specifically for education that you repay after Graduation with your Masters. Good luck and do stick with it. As long as you keep wanting to take a step towards a Masters Degree you will get one.
