Help Maria Walk Again

My dream is to walk again. I suffer from a rare disease causing short stature and complications with the bones and joints. In this case, the condition has led to weakening of the joints. I have been unable to walk for 3 years now, and only recently have started a treatment in the rehabilitation hospital "Serdika" in Sofia. The treatment needs much financial support and shouldn’t cease at this moment, when some improvement has already been noticed.
I need an endoprosthesis of the left knee joint and my family is unable to meet the costs. I already hardly survive economically because of the expensive treatment and previous medical interventions. I need your help to make my dream to walk again come true.
Thank you to everyone for your support!
