First Breakdown

So I've already had my first breakdown, and my internship hasn't even started yet.  I'm thinking about how much I have to get done in the next two days before the internship starts, and I just can't imagine how I'm going to do it all.  I got an email yesterday saying I'm supposed to have read a book off the summer reading list, as well as complete a writing assignment along with it.  I also am supposed to read another short story, the school goals for the year, teachers' reflections from last year, and one more thing that I can't remember right now.  They all have different deadlines, and I'm really confused about the schedule for the next few weeks.  I hope it all gets straightened out when I show up on Friday.  In the mean time, I'll try to stop crying and tell myself that it will all work out.  I hope I'm overreacting, and it only gets better...
