Just me... But I usually put those things in "Depression"... I guess because I've usually posted about being depressed and that's where people would see those posts about how sad or bad I feel, so those same people would see that I'm feeling better now. That thought extends even if I haven't posted recently about any specific depression.

I guess I consider it a "not depressed" post which goes under the category of depression.

If I had posting in Bipolar I would put that in the Bipolar forum... categorizing it as "not suffering from bipolar symptoms today".
