Suggest me a non-sappy, non-sad litfic

PLEASE help me. I haven't got an answer from this I was happy about.

I am practically moving on from fiction. I love the genre but it is so sad at times.

Classic literature is almost always sad or satirical, two genres I've grown tired of. And this is to no offence to anyone who likes it, I am just dealing with a LOT and this is NOT for me right now.
– Death is not sad, untimely deaths are, a la Foundation series, even so, it depends, a la Beowulf
– Warm doesn't mean it's not sad, a la A man called Ove (he tries to kill himself, and he doesn't but it left me weeping anyway)
– Violence doesn't mean it's sad, a la Mistborn
– Non-sensical "nature of man" type sadness that is avoidable is sad, a la Stoner
– A Gentleman in Moscow is depressing because he is on house arrest
– A good ending doesn't make the story not depressing, a la One Hundred Years of Solitude
I literally just want a book in which a character has some struggle, and becomes successful, end story. I know this doesn't make for a good conflict, but I need good books. I don't need YA (I hated Legends and Lattes because I wasn't the audience for it), I need literature. If you have a good fiction suggestion, I would love to hear it too. No satire either.

I don't know what happened, epics are relatively positive. Beowulf, Odyssey, Aenid, Gilgamesh, even Illiad, or Mahabharat with all its violence, or what have you. Even in modernist times, Henry V, Pymilgian (that GBS play I am forgetting), etc. feel generally fine. King Lear gets a bit depressing etc. But modern works WANT you to be sad, I don't know why. Either sad or coddled. There's no great Arthurian style legends anymore. Did people just lose the lust for life? Does everyone need to humbled? Is everything a slice of life now? In the days of serfs, we had hope, and in the days of hope, we have bleak and despair in our media. Why, I ask.

Books I've read and find depressing:

1. Stoner
2. East of Eden, sometimes
3. Tortilla Flat
4. Moby Dick
5. Absalom, Absalom
6. Madame Bovary
7. Anna Karenina
8. A Farewell to Arms
9. Anything by that weirdo Nabakov, but I made the mistake of reading Lolita because I listened to reddit
10. Rushdie's books
11. Literally any word ever written by Dostoyevsky
12. Hamlet (love stories are poorly written anyway)
13. Les Miserables
14. Flowers for Algernon
15. Songs for Solomon (still finishing up)
16. All Quiet on the Western Front

And many more. There was a time in my life I could read these just fine, I can't anymore. Life is very heavy. Please help.
