I would say work on pronunciation. If you improve your pronnunciation skills, it will be easier for others to understand you and eventually your accent won't be an issue at all. Everybody has an accent, even native speakers from different regions have one, and at some point it might be something that you don't want to completely lose, like a personal branding thing or something that makes you unique. But pronunciation is important because some mispronounced words might make it difficult for others to understand you.

Just keep practicing. In my personal experience, it helped a lot to watch comedy series, and movies without subtitles and training myself to identify the sounds and expressions used.

I graduated from Salesio Girl's Highschool in Korea which is a mission school in Korea. The school was really good. I liked the atmosphere of Catholic, good teachers and students, beautiful campus and so on. I'm not Catholic, but I enjoyed many events releated with catholicismCatholic. Listening and singing the sacred songs helped me to be peaceful and release some stresses.
And teachers were good. My favorite teacher was the Geography teacher. He was very short and funny. I still keep in touch with him by SNS. His teaching ability was not good (He just readed the textbook loudly in front of the classroom), but when he was in the classroom, all the students didn't dozed laughing. I used to wait for his class all day long. 
Also there was a terrible teacher. He was very handsome, but he liked only pretty students and even told them pick up lines even though he's married. Last year I heard that he got divorced because of his cheating. He had an affair with a his student. What a shame!
