Brief Answer:
paroxetine is the best drug in my opinion

Detailed Answer:
Hello,

Thanks for writing to us.

Best treatment of generalized anxiety disorder (GAD) includes both medicines and cognitive behavior therapy (CBT).

In mild cases only CBT is sufficient. In moderate to severe cases initially medicines and then CBT is added. And later on medicines stopped gradually.
If medicines alone are used chances of relapse are more after stopping the medicines.

In medicines SSRI group of drugs (fluoxetine, paroxetine, sertraline, escitalopram) are main stay of the treatment. I prefer paroxetine. Benzodiazepines group of drugs (clonazeapm, lorazepam or etizolam) are used initially for short duration for fast symptomatic relief.

You are already using lorazepam and trifuloperazine in low dosage but those are only symptomatic medicines.
Gabapentine is used in GAD but it is second line medicine after SSRI.
Benadryl is not all indicated for anxiety. If you have any ENT problem, it is ok.

If I were your treating doctor and your diagnosis of GAD was confirmed, I would like to go with paroxetine, clonazepam and CBT.

If you have not consulted any psychiatrist yet, please consult soon, discuss above points and change treatment plan.

Hope I have answered your query, I will be happy to help further.

Regards,
Dr.Chintan Solanki.
