Those sound very much like hypomanic symptoms to me. Not all hypomania feels euphoric, so being energetic or having a racing mind but feeling down may be more like the agitated/irritable or mixed states sort of experience.

I've definitely had meds provoke that kind of reaction (temporarily) which demonstrated that it was doing something against the depression. Adjusting meds also made my moods change much, much faster than I was used to experiencing - more ups and downs a lot quicker than usual. After awhile those effects went away.

So no, I don't think you're really the only one that feels like this, and I don't think it's all that unusual when getting adjusted to new meds.
