There are also different degrees of mania. You could be experiencing hypomania, which is a milder form. There isn't quite the soaring mood, but more like a "really really good day", along with some of the other symptoms you've mentioned...the shopping, the sexual impulses, the excessive or inappropriate laughter...one of the big things I watch for is a lack of sleep. If I'm running around on 3 or 4 hours of sleep, feeling great and resenting even the thought of having to sleep because I have all these wonderful plans...that's a sure sign that I'm getting manic.

Were you on any antidepressants during your euphoria before your psychotic break? If not, does your current pdoc know about it? You can have symptoms of both a mood disorder and schizophrenia in something called schizoaffective disorder. But your doctor is right, technically he can't call it true mania (at least not where I live) if it only happens when you take an antidepressant. But mania (or depression) can also include psychotic features. It's a very murky pool to sort out sometimes. But I would try to take an honest look back to see if you can remember any periods of your life that your mood was, maybe not truly euphoric, but more elevated than usual and you had some of those manic behaviors. Or elevated and really really angry or agitated. Your doctor needs to know about them.
