Many Doctors are leery of prescribing a Benzio due to the ability of an addiction to happen. There are many AD's that actually do help with anxiety quickly, Maybe your Pdoc would be willing to give you a small amount just to take the edge off until an AD starts to kick in.
I will say as a person that has been on Xanax for about 6 years.. My body has a physical addition yes , if I go without I will become physically sick. But I am not mentally addicted , that is a huge difference, If my doctor and I decided I should get off it , I would need to go IP for a detox so that they can monitor me 24/7 and give meds to counteract the possibility of seizures and stuff as that is a real threat.
Anxiety can be a horrible thing to deal with. There is a Member that frequents this board name is Zinco he has vast knowledge on psych meds , feel free to PM with questions about maybe an AD that has the ability to decrease anxiety quickly .
I hope you find a way to manage your anxiety and feel better soon.
