The show treated his attitude as a huge flaw. I interpreted his character in earlier seasons as despite being a genius in many ways, he was still an immature child. He was often ungrateful for his parents’ sacrifices and unempathetic to those around him, like a lot of kids his age. He even had trouble making friends because others found him difficult to be around. As annoying as he could be, I think it also made him a more realistic character and set him up for later character development.
Sorry to hear things are rough, I hope you get some reccs you like ❤️
I thought In Stars and Time was really uplifting, but it does deal with mental health issues throughout the game. One of my absolute favorites and something I go back to in rough spots tho :)
Fields of Mistria is similar to Stardew. Its still early access, but there is a lot to do in the game as is. Traveller’s rest is similar to Stardew, except you have a tavern.
Tiny Glade is good if you like sandbox games. Minami lane is also alright.
For adventure games, I thought Caravan SandWitch was fun, kinda bittersweet. I havent finished Snufkin: Melody of Moominvalley, but i would be shocked if it wasnt uplifting. Islets and Crypt Custodian are also nice metroidvanias. I thought they were both funny and cute.
