My hobby is learning a certain language but idk if I should continue it

My hobby is learning a certain language but idk if I should continue it I like learning Korean. I've been learning it for 5 years. I take online lessons and talk to Korean coworkers in my real life. I stutter in it and OCD also manifest as part of my stutter. I will have an obsession with a word and my compulsion is to say the word out loud or in my mind repeatedly. Sometimes I don't know if learning it is really a hobby.. I mean, I like it. And I've reached past beginner but sometimes studying it feels like I'm creating trauma to my brain because I will start stuttering on things that I didn't stutter before. And then I will panic and then the OCD will making things go downhill.
