Do Texans discriminate against non-Texans?

My family and I moved to Dallas about 5 months ago from Jackson, MS. The advertising market is booming I came to be a part of it. (I have 15 years experience) Since arriving, my wife and I have had a lot of trouble finding work. (She had to take a job as a cashier- far below her abilities) and I have had trouble even getting interviews. Also, my daughter is constantly ridiculed (even by teachers!) for being from Mississippi. I also have felt I was treated as if I were stupid during the few interviews I get. I had high hopes and was excited about moving to DFW, now I am miserable, broke and getting more bitter every day. Is there any truth to my growing feelings of resentment? I need to know.
