So I don't think I have GAD at all, I think I am bipolar II, but my mania is anxiety. Or it's mixed states. Or agitated depression. Here's why:
1 - Anxiety has not responded to standard treatment of antidepressant plus benzo
2 - Anxiety is cyclical, can go away for weeks, kick on like a switch is thrown
3 - Anxiety is very high excitement, very high energy, but not full on mania
4 - During a cycle, need for sleep is decreased
5 - Had a doc diagnose me with agitated depression, right before ECT, actually, which is mixed states which is in fact a form of bipolar, though I will say he was the only one whoever made that diagnosis.
Try a course of Lithium. If it works, there you go, anxiety was mania, or dysphoric mania, or both, they do co-occur I realize.
Why do you think anticonvulsants are so effective for anxiety disorders?
Just saying. Am very into action mode at the moment, looking at very expensive inpatient options with intensive evaluations.
