Hello, allbeengone &
I'm happy for you that your wife is considering Therapy; it's the first hurdle she needs to jump on the road to recovery, and I sincerely hope that she follows through with it.
I am not in the Dallas area, but I do have a site that should be able to help you find the information you are looking for:
NAMI: National Association for Mental Illness; there is a search bar on that site you can use, besides all the information on that page.
Maybe someone familiar with the Dallas area can help you, but NAMI is a great place to start... .Good luck, allbeengone. It sounds like things could be looking up
