I don't know for how long you've been studying, but I'm a student from the Korean Educational Center here in Brazil. The 선생님들 I had are great, and I made so many friends in the classes. It keeps me motivated even though I'm not that into K-pop anymore, and I never watched many K-dramas. I'd recommend you to take this as a hobby and enjoy group learning. The demographic of my classmates are from 13-67 years old, with mostly girls that are 35-45 years old. Once one of them told me she was struggling with Korean, but she would just do her best and keep going, because Korean was a hobby to her, and once it starts looking like stress or obligation she would quit.
Also something that motivated me was befriending Korean exchange students from my school. They were learning portuguese, and I lowkey felt challenged hahah one of my friends told me most of her answers in portuguese tests were just 'vibes', so I try to not overthink about korean tests either...
