How efficacious are hydroxyzine pam, gabapentin, low doses of trazadone for treating anxiety, aas per peer-reviewed research? none have worked for me.

SSRI's more helpful: For anxiety, ssri's such as celexa, lexapro, & zoloft and snri's like Effexor (venlafaxine) have more research support behind them than those you've mentioned. You could see a psychiatrist for a thorough evaluation and treatment recommendations -- might be time and money well-spent. Your info says you're also involved in "behavior therapy, " and what's being done there can be reviewed also.
