Help me safe my house and my son

I am a 26 year old single mother to a beautiful son who is 7 years old in April , I am currently living in abu dhabi while my son is in South Africa with my parents , we have recently hit a really tough time . My father is i'll and not working and only my mother is working but the money I earn here and send home is not enough , we recently got notice that I am behind in the payment of my house and that the bank will take it away leaving my son homeless and my parents , I have sent everything I can and all that I have. I would like for him to come and stay here but having no support and being the only parent it is extremely tough . I am a proud person and I have hit rock bottom I don't know what else today and I fear that I may loose everything I have worked for since childhood.
