Prew,
Don't think of it as failing...you just didn't have all the tools and help in place that you needed at that time. This time, you do...so it will go much better!
With therapy, your coping skills, and possibly an alternative medicine to help you get through any trouble spots, you will find it much easier to reach your goal.
Ask your P-doc about
Vistaril. (hydroxyzine) This Rx is an antihistamine (taken off label for anxiety) that is used like a benzodiazepine...but without the risk of dependency. It could be just what you need if you encounter any rough spots during your discontinuation.
Let us know how your appointment goes. I do absolutely believe in your ability to do this.
We are cheering you on friend!
S.C.
