i agree with roadrunner, a nurse has no business diagnosing you. on top of that, i feel they are way to quick to diagnose people with borderline personality disorder which shares several symptoms of not only bipolar but ptsd as well. so it is often misdiagnosed.

the important thing to stress when you do get in to see the psychiatrist is that you feel the lithium is working. pdocs are pretty good about leaving people on a med if it is working.
