I'm not feeling well.

The various strains of illness that have been swirling about me at home and at school have finally overcome the outer wall of the Helm's Deep of my body's immune system. The super-Urukai of disease charged in with its flaming torch of illness and suicide-leapt itself onto the hidden store of infirmity brewing and stewing beneath my afor-mentioned walls of eudaemonia.

.... in other words - I'm not feeling well.
