The thing is, you can be stable, but still at a low level of depression. So it matters how you define stable, or how your Pdoc/T define it. Is it happy, or just a lack of mood swings?

If you are aiming at happy and your chart (I'm assuming this is a mood chart?) shows you with no mood swings but still at depressed, then you are safe in saying you are not stable.

I consider myself quite stable, but still with an underlying depression that has been here since 2003. But it's an even keel depression. So I guess my definition is lack of mood swings.
