Any suggestions as to how to find drug rehabilitation centers in Mexia, Texas?

I have a friend who idolizes someone who used to do heroin (that person’s dead now). I guess my friend really wanted to know what her idol saw in heroin that she began trying it too, and now she’s hooked. I want to help her, even if it’s just by finding a drug rehab for her. Any suggestions as to how I could convince her to get herself treated too?
