Hi;
I Googled the question, "Where are anxiety support groups in Houston" and this is only part of what came up.
www.shyness.meetup.com/cities/us/tx/houston
www.freedomfromfear.org/supportgroup.asp
www.anxietypanic.com/texas.htm
www.211.org (anxiety support groups)
http://www.healsocialanxiety.com/ (free conference call-type support and face-to-face groups)
At first, you may want to try an anonymous, conference-style support if going out of the house is too anxiety-producing. If that's not an issue, check for a group near you.
Happy Independence Day!
