i love cartoons. also adventure time (duh), futurama, inside job was good, midnight gospel, and the second best hospital in the galaxy. if you want to be a bit bummed out you should probably watch bojack or moral orel (claymation actually)
go for a walk. let your mind wander. think fluidly and let your mind go where it takes you. take out that phone if you have questions you want to google, but try to solve problems on your own as much as you can. ask yourself what sparks your curiosity, your joy, what feels meaningful. try to find a book or podcast or something about that and use that noggin'
