Translation:

Loving as I loved you is a self-inflicted, incurable wound waiting to happen. Because my feelings for you have started growing again, I’m having more trouble than usual getting you off my mind. What else is to be expected? You’re who filled my life with joy, and when you left I became much like a man walking in the dark, stumbling in almost every taken step. Nonetheless, deceitful one, regardless of what becomes of me — whether on earth, in heaven, or hell — I’ll be sure to say a prayer for the benefit of your soul.
