lifelost 

Feeling as if one has no purpose in their lives, creating a melancholy, listless feeling.

1. After getting dumped by his girlfriend and fired from his job, Milton felt pretty lifelost.

2. Due to his intense philosophical nilism, Milton felt lifelost, purposeless, and numb.

lifeloser 

A person of small stature from Canada who's own life is so bankrupt that he spends every waking moment trying to berate people on Internet messageboards with lame, unwitty insults.

Yeah that trust guy is a real lifeloser.
