Bundle of Emotion

I have been feeling a little overwhelmed and stressed lately. I just moved into my new apartment and have been busy unpacking and organizing. With school starting in 4 weeks, I am starting to feel the pressure of getting ready for this school year. I have so much stuff on my To-Do list but I have no clue where to begin. I have been working on my Classroom Management Plan and thinking through various routines and procedures. I am currently working on setting up my class newsletter and intro letter to my students' families. I have also spent quite a bit of time reviewing curriculum, but now I feel like I need to just start planning. I would love to meet with my grade level teachers but I do not know who they are (long story) and my principal and vice-principal are on maternity leave. Needless to say, I am a big bundle of emotions right now!!! Advice....suggestions on how to effectively navigate these next few weeks?
