sandbox mode is very easy to get familiar with and can give the game a whole new dimension of interesting playthroughs, it's very rewarding to create your own perfect personal survival experience, and that's omitting the wonderful workshop integration that makes it very easy to experiment with different mods that can basically give you an entirely tailored experience just for you. that being said, from what you wrote it seems like you are just burnt out on this title or in videogames in general. take a break! go learn an instrument or start running or something! too much of the same thing is never good
