Please help me to help my mother to have a good retirement

I find myself looking for funding to improve the retirement of my mom, due to the crisis facing my country Venezuela I had to leave more than a year ago but with the misfortune of leaving my mother alone, I have no brother or father, she is with a cousin who takes care of her but only couple of hours a day. My mother gave me education, care me as a single mother even though I'm not her biological son. She has an undiagnosed disease similar to amyotrophic lateral sclerosis, the disease that became famous after the ice bucket challenge, her muscle capacity has been degenerating over the years, since 15 years ago. My mom has suffered numerous fractures (hands, legs, hips) and a countless amount of shock and trauma. These years have been difficult that is why I want to give happiness to give a trip so she can be with me and care as she deserves, to give she the attention that in so long I could not. I am actually working but I have hardly safe for the airline tickets but please help me to give a good trip for my mother, I will hardly pay for food but she deserve much more than that. I really need your help to improve my mom’s life, she deserves it. I will always be grateful to anyone who wants to help me and especially my mom will be.
