OP, I can tell you, everyone *I* know that has come back from Dubai, has loved it here.
All the people telling you that whites can't get employment, are white and employed.
There is a lot of **** in the country, but there is a lot of **** in every country. Your mom has good intentions but you DO have to leave Dubai, so there isn't many places you can really go. When you get here I am sure that you will have a great time, being close to family and seeing our beautiful country again. It takes a while to adjust and everyone is different, but give it a chance
