Do you go on two types of medications at the same time, is therapy effective, etc.?
Sometimes the mood stabilizers used to treat bipolar disorder can also "treat" anxiety as a side effect. That is, if the anxiety stems from the bipolar disorder (which it sometimes does), then treating the mood disorder will also treat the anxiety because the anxiety isn’t a separate problem of its own, but rather a byproduct of the bipolar disorder.
However, I’ve seen a lot of your posts in the past. You have said that you suffer primarily from anxiety, and that you didn’t even consider bipolar disorder as being a possibility until your psychiatrist brought up cyclothymia. Have you gotten a second opinion on that? Has another mental health professional corroborated the diagnosis of cyclothymia? If you are unsure about your diagnosis (which you have certainly seemed to be in the past) you should seek a second opinion, just to make sure you’re being treated for the right thing. Since you never noticed your mood as being a problem in the past, a diagnosis of a mood disorder seems a little odd to me.
There is a type of therapy called cognitive behavioral therapy (CBT) that is extremely effective in treating anxiety disorders of all kinds. It addresses your thoughts and the resulting anxious behaviors, and by changing (or "restructuring") your thoughts, allows you to change your behaviors and beat your anxiety. Even if your anxiety does stem from bipolar, which is questionable at this point, it will help you manage your symptoms in a much better way with or without medication.
Good luck.
