"Repetition is the killer of all emotions"
Even what you like can turn into a shore. Even sometimes in novel, i seen some urban (chinese) characters mention "it's fine to keep it as a hobby and not a job, because if it become a job, it would lose it's charm"
Same with love. Lot of cheating is because the married people are tired of their lovers. Also lot of divorce is because, beside finding out the other is not fitting, is because they lose interest. ALSO the idiom [get some distance so the relation stay fresh] works as a contrary solution.
And horrible with inconvenience. Sometimes slightly bothersome can become rage-worthy, depending on how often it will happen.
Even in torture, this logic was used in WW(2?) or before. Simply letting a prisoner have a drop of water fall on his head every X seconds.
FOOD itself is probably the easier thing to understand this. Not often you will find normal families eating the same dishes for 5+ days. YEARS years ago as teen, i saw once on youtube(or tv), a dude doing experiment eating only hamburgers for a month. Result, body itself couldn't accept and he vomited at end of the month when trying to eat more of them.
Music. Happens to probably MILLIONS or billions of people. Them being tired after listening too much to one song. But not lot of people thought of thinking the reason, which simply "repetition" / I am a loop-addict of some good quality songs, and it's interesting that some particular songs are more "durable", because the song itself have multiple different things itself. A song with different parts, makes the brain not tired easily of it, because it's simply like listening to different songs.
EVEN the very old manga Yakitake Japan (bread manga), drew a bread that is impossible to tire of. It is the arc where the samurai guy fight vs the pastry girl (marry to him later), and the bread had a sugar flower on top. Ignoring the flower, the bread basically had multiple "stratums" of different kind of tastes. Lastly. It's also why the chinese fried rice (of putting any kind of ingredients together) is a masterpiece and not tiring to eat endlessly.
tl;dr : Simply take a break. And do other activities for fun. Even a videogame can be tiring if played non-stop.
