You are certainly not wrong Merika. Let me clarify:
The term melancholia originated from the Greek, and originally served for psychological personality description. Choleric, phlegmatic, sanguine, and melancholic were these 4 different temperaments.
Since then it has had a few different meanings - often though the positive aspects of the personality description disappeared in our languages. Which in turn creates confusion as to what you mean when you use the term :?
http://en.wikipedia.org/wiki/Melancholia , which explains a bit on the whole controversy on what melancholia is.
