sooo overwhelmed....calling all teachers

So I met some of my students today and I felt like I was all over the place. Please tell me teaching gets a little better once the school year starts, I feel like between all the clerical work, getting to know the students and giving them the rules I'm going to lose it.

My school has half days tomorrow and friday so I'll only be able to give the rest of my kids rules, rules, rules, their seats and their textbooks. Monday I start my lessons but I feel so disorganized.

Please tell me it will get better once I get into the groove of things....The Principal even laughed and said to me 'you poor thing, you look like you don't know up from down right now' then she told me not to worry....
