I've heard of people (like myself) who have bipolar, but have been misdiagnosed with unipolar depression. I don't think I've heard of a pdoc giving the dx of bp without any signs of mania or hypo mania. Since you are doing well on the Lexapro, I doubt you have bp. Usually anti-depressants will throw someone with bp into a mania. Glad to hear you are doing so well. Have you changed psychiatrists? I probably would.--Suzy
