Thanks for your query at DoctorSpring.com.
I have gone through your question in detail and I can understand what you are going through.
I totally agree with you that a resistant depression and anxiety is very troublesome and needs proper treatment. You have mnetioned two of the medicines but i suppose you have also been tried on desvenlafaxine or paroxetine as these are certain drug of choice for anxiety with depression and are very effective.
Also coming to the topic of benzodiazepine. Yes they have an addiction potential if used by own. But when used therapeutically under a doctors prescription then they are quite safe amd effective as well for anxiety. You should certainly ask your psyhiatrist to give you a trial of clonazepam or lorazepam. If your anxiety is resistant, you do deserve a trial of benzodiazepines. I usenit very frequently in my patients and its very effetive and easy to get one off it as well.
Hope this helps.
If you have any furter query, do let me know.
