major depressive disorde
"Prevents dwelling on missed loved ones, crying, irritability, feeling left out, self-pity, resentment, bitterness.
Has either hurt or failed to help low energy  level, motivation, task initiation, and focus
Worth it and would not want to try to live without it.
If I miss a dose all that first paragraph stuff comes back but the worst is the physical brain zaps and dizziness upon standing & walking.   If I miss it for 2 days or more, I get a fever and flu symptoms."
