Have you sufficiently researched how to lower the dosage? It is important to do it slowly and in small reductions. I filed a complaint with the FDA that this drug is not supplied in smaller amounts, so as to facilitate withdrawal. Unless they receive a barrage of complaints, however, the FDA will do nothing about it.
The UK now requires warnings about this drug; it's called informed consent. Sadly, it is not yet required in the United States.
I am sorry you have had a bad experience with a "Medicare Advantage" plan. After witnessing the nightmare my parents went through while enrolled in one, I never recommend it, if one can afford to stay in Medicare.
Please learn some tips and tricks to lessen your worries! You can find helpful hints on this website. My anxiety ballooned during withdrawal; I had to resume this drug (at a lower dose than I was on, thankfully), but learning coping techniques is invaluable. Good luck and best wishes to you.
