First day of teaching

Today was my first day of teaching. I did not cover much, but this was a stressful day. I am temporarily on overload. I teach 7 subjects, which require a lot of preparation. I am exhausted today. i only went over rules. I am a bit worried because I began my own course work today and it seems like it is going to be a stressful and busy 10 months. I am almost wondering how am I going to fit in any cultural exploits. I am sure I will figure it out. I think I will head to bed early tonight. I need to recharge for tomorrow.
