What does unhappiness feel like?

Seriously, I am not sure that I know the answer to the question, and am demonstrably nervous about not knowing and decidedly uncomfortable with being unsure about whether or not knowing is even a desiderandum at this point.

I thought about undertaking an indepth investigation of this issue as it relates to current circumstances and appurtenances as well as to broader and less personal issues about the medicalization and commercialization of our own understandings of our subjective states - the elimination of the aesthetic melancholy in favor of the clinical depression or even the mercantile unhappiness (to be transmuted into happiness by the acquisition of goods and services). Instead, I will forgo all of the above in favor of dinner. I also feel that undertaking a rigorous examination while hungry may unduly prejudice the answers as there is a certain degree of, er, tortellini.

Note to self: If it is called De contemptu mundi it may be the exact wrong thing for a down day or rather too much of the right thing.

Est ubi gloria nunc Babylonia, nunc ubi dirus
Nabuchodonosor et Darii vigor illeque Cyrus?
Qualiter orbita viribus incita praeterierunt.
Fama relinquitur illaque figitur; hi putruerunt.
Nunc ubi curia pompaque Iulia? Caesar, obisti.
Te truculentior, orbe potentior ipse fuisti.
Orbis ut extera sanguine, sidera laude subires,
Mota furentia sunt tibi brachia, proelia, vires.
Cum genero sene brachia non bene conseruisti,
Nec socer illius aut socius pius esse tulisti.
Qui cinis es modo, tantus eras homo, quantus et orbis.
Vi tibi subditus extitit ambitus urbis et orbis.
Ecce resolveris area pulveris, urna favillae;
Caesar et nudus es et prope nullus es; O ferus ille!
Nunc ubi Marius atque Fabricius, inscius auri?
Mors ubi nobilis et memorabilis actio Pauli?
Diva Philippica vox ubi coelica nunc Ciceronis?
Pax ubi civibus atque rebellibus ira Catonis?
Nunc ubi Regulus aut ubi Romulus aut ubi Remus?
Stat Roma pristina nomine, nomina nuda tenemus.
