I wish I had time to do things that I want to do.
These days I have been so busy. I am getting used to my new workplace. However, I do not yet understand every situation in my hagwon (What is hagwon? What did you mean). It is Friday night but I can not enjoy (?) my Friday because I have to go to work.
My middle school students are preparing for the final exam which is going to be taken in 3 weeks. Also, I have a lot of things to do this weekend. I wish I could just relax, doing whatever I want to do.
You know what [bothers me]? How busy I have been lately. With no time to clean up, my house is getting messy. Also, my heart and mind are messy also, since I have no time to think about anything except work.
[I hope I understood what you were trying to say and that my corrections will help you. Very good work!]
