Best medicine for anxiety and depression disorders?

The three drugs that you mentioned are all antidepressants, not anxiolytics. It is possible that they could help with your anxiety as well, but that is not their labeled use.
I am antidepressant treatment resistant. So I will never take another antidepressant again. For me, the side effects are unbearable compared to the extremely limited benefits.
However, for my anxiety, I am currently on clonazepam, 1 mg three times a day, and I find it to be very effective. I have been on quite a few anxiolytics over the past two decades, and I find that clonazepam is the most effective one for me at this time.
I'm sorry I was probably not much help, but I do hope that someone else can better assist you.
Best of luck always.
