Thanks for the question with god description of your case. I do understand your effort and discourage. Response to medications in GAD is usually not very good. To my mind, alternatively, you may be suffering from anxious avoidant personality disorder
. However, if your diagnosis is GAD for sure, you need to use the drug in adequate dose for an adequate period ( may be 2-3 months) with good compliance along with CBT, RELAXATION THERAPY
, activity scheduling all to be started simultaneously and continued concomitantly. Non-pharmacological measures have might work better than medications in some cases. If it is anxious avoidant personality disorder, expectation need to be lowered, but with continuous professional guidance dysfunction arising out of your condition can be better. Wish you good luck.
