I can’t answer your question but I to am older, at 76 and have a lifetime of depression and anxiety. I’ve tried many drugs but what finally broke the code for me was 4 mg of klonopin and a tremendous therapist. The klonopin got my anxiety down to where I could work with my therapist and get to the root cause of the problem. I was able to get off the klonopin very easily using a step down approach with my psychiatrist. Good luck.
