Earnest creation requires some sort of passion for what is being made, whether it's a child drawing something for the fridge, a professional journalist working on the big scoop, or a scientist Creating Life, and everything in between. When that passion is gone, so is the will to create.
So, when these creative types become emotionally wrecked, their passion tends to leave them. They don't want to work on their new novel or finish up that painting they've been obsessing over. They just want to do nothing— or worse, they want to destroy their creations. Their ability to create leaves them entirely, and even if they make an effort, they will find they just can't do it. Not in the way they could before, at the very least. This is especially likely if their breakdown was caused by something related to their creation.
Undoubtedly, this shift will worry those around them, who are used to this character being interested in their craft. They may try and help the character regain their creative spark, but it's not always possible.
This is Truth in Television. Depression can make people lose interest in things they once enjoyed, and this includes creative endeavors. That said, not every example of this trope is going through an actual depression; they may just be going through a rough patch.
- In Charlie and the Chocolate Factory, when Mr. Wonka goes into depression, his creativity goes downhill, and the chocolate factory faces harder times.

- Cataclysm has a morale meter that is affected by things like the food your character eats or the weather. If morale gets too far in the negatives, you are locked out of crafting or repairing items until you get it back up.
- The title heroine of GRIS starts out so broken by grief that she cannot produce anything but weak gasping sounds when the player presses the button labeled as "Sing".

- Layers of Fear is centered on a Mad Artist who is struggling to paint his magnum opus, but has to search his house for items to do so. It's implied later on that his lack of will to paint stemmed from his wife's injury in a fire, and eventual death, and all the artist has left is trying to recreate her portrait. His skill returns little by little as the painting takes form, but 3 different endings vary on what the final result becomes.
- The Cry of Mann: Jack starts off as a completely obsessive artist, and though he was only painting one thing, his family still had respect for his talent and passion. That is, until his art show, where his chosen subject matter of orange phones sent everyone into a mass, unprovoked, fit of rage. After that, Jack became so angry at everything in his life that he destroyed his paintings, and lashed out at his family members and his callers. By the time he became "Jack Prime", his anger had consumed him, and his interest in art was gone.
- My Little Pony: Friendship Is Magic: Rarity suffers this twice:
- Shown in a Yet Another Christmas Carol plot in "For Whom the Sweetie Belle Toils" when Luna shows Sweetie Belle what the consequences of her actions in sabotaging Rarity's headpiece for Sapphire Shores will be if she doesn't fix things. Namely the headpiece falls apart when Sapphire tries it on during a dress rehearsal, Rarity loses her credibility due it, obsesses over the mistake to the point she won't even speak to her friends anymore and ultimately stuck in a fetal position while her dress shop falls into ruin.
- Happens again in "Inspiration Manifestation", though this time due to Rarity not designing a cart for a puppeteer properly and getting chastised for it. Spike finds her in the dress shop suffering Heartbreak and Ice Cream, which prompts him to help her gain her spark back via a ominous-looking book he finds in the Castle of the Two Sisters.
- Phineas and Ferb:
- In "Phineas And Ferb Get Busted", the boys are sent to a reformatory school after their mother catches their latest project.

By the end of it, Phineas and Ferb are shells of their former selves, and can't create anything. Luckily, it was All Just a Dream.
- In the "Summer Belongs To You" special, in which Phineas and Ferb travel around the entire world to have the longest possible day of summer, they end up stranded on an island.

Isabella has to snap him out of it as he gets more and more desperate.
- SpongeBob SquarePants:
- In "Pickles", SpongeBob gets so upset about forgetting to put pickles on a Krabby Patty that he is unable to remember how to prepare one. It gets so bad he can't do anything at all, even talk with proper syntax. Once he is able to relearn how to make a Krabby Patty, he returns back to normal.
