Amazing description of depression:

Zle, zle, zawsze i wszedzie
Ta nic czarna sie przedzie:
Ona za mna, przede mna i przy mnie.
Ona w kazdym oddechu,
Ona w kazdym usmiechu,
Ona we lzie, w modlitwie i w hymnie.

Ill, ill at ease always and everywhere
A black thread is weaving itself
It's behind me, before me, and all around me.

Running through my every breath
Through every smile
Through every tear, prayer, hymn.

By Polish Romantic poet Cyprian Kamil Norwid
