Depressive Curse

"Greyback standing behind his unconcious body, realizing that the Order has arrived, quickly pointed his wand at [redacted] and uttered "Amouri Damnum". A jet black light had struck his already shattered heart, shattering it even further. He's alive physically, but remains dead inside."

- Fenrir Greyback, using the curse at [redacted] after realizing the Order of the Phoenix is on to him.

The Depressive Curse (inc: amori damnum) is a curse that can inflict severe psychological pain. Since November 2021, it is an unforgivable curse.

Although the curse cannot be reversed, there are preventative measures one can take. For instance, one may dodge the black bolt, block it with a physical barrier, any living thing not a human or goblin, a magical creature, use of the Killing Curse to trigger Priori Incatatem. The Depressive Curse, just like the Killing Curse is considered 'unblockable', thus shield charms won't defend against it. If it hits something non-human, then a black cloud similar to which when a horcrux is destroyed will emit (when destroyed via the Sword of Gryffindor or the Basalisk Fang). If left untreated, the victim will relive any traumatic events he or she has experienced during his/her lifetime.

Like the other unforgivable curses, there is no counter curse, but unlike others, it can be treated surgically if caught early, as the decay from the curse spreads to every part of the victim's body internally, making it impossible to remove.

Survivability
Chances of survival of the depressive curse is very slim. Unlike the Killing Curse, the Depressive Curse (is still fatal) is a slow and very depressing way to die if the effects are not treated at all or correctly.

Etymology
The incantation, amouri damnum, is Latin for Love Loss, but damnum, closely related to damnare, which means damn. However, it's actual meaning is: let the heart be shattered. Either way, it either means love to be loss or love to be damned.

Trivia

 * In the Fifteen Reasons Why MMO/RPG, if you are hit by the curse, your max hp is set to 1% for 60 seconds while the curse is in it's preparation. During those 60 seconds, you are in combat. Teleport scrolls will not work, and logging out (by force-quitting, or by entering character selector menu) will kill you, but the curse will remain either way. The same goes for the Cruciatus, except your max hp is set to 25% and the Combat will end after only 10 seconds as opposed to 60 seconds. This makes (theoretically the) fourth curse extremely deadly if you are caught with it, since you are basically put down to a one hit kill entity, by any mob or player. Even a simple breakup when under the influence can kill you instantly.
