Not sure if any body else caught on to this train of thought, but I perceive this that his love has left him - "Where have you gone now?" - and to be together he'll take his own life - "This is my farewell...".
It might seem drastic, but think about it; everything is personal, and the person continually refers to them as 'we' and believes that he himself can solve the 'problem' - "I'll wait" - "I'll carry" - "I'll meet" - "I'll see".
