I'm surprised that your doctor refused you anything for you anxiety. My T couldn't get the thoughts in my head to quit spinning. My mind races non-stop. So my doctor on Klonopin. I know the drawbacks from taking it but I do get peace of mind from it.
I hope dealing with it in therapy works for you.
