Am I an overprotective emotional basketcase or what?

I guess this is why I have a blog; so, I can write needless thoughts to myself (and allow others to read them if they are bored) and hope I feel better in the long run. I'm about to do just that...
I just dropped Ian off at school and embarrassingly 1. told the secretary her rules were ridiculous 2. cried in front of the principal 3. boo hood all the way out to my car 4. just now gained composure (20mts. after leaving Ian). BUT I DIDN'T CRY IN FRONT OF IAN!!!
Why you wonder? B/C Ian has had some weird virus for the past 4 days - missed two days of school last week - keeps breaking out in an itchy rash, which I was told wasn't contagious, and then last night got knocked over so he has a huge goose egg on his forehead and had been asleep since 6pm till this morning. So, I told him I would walk down to his room and explain all that to his Pre-K teacher since she has NO PHONE NUMBER OR E-MAIL ADDRESS FOR ME TO GET IN TOUCH WITH HER! I go sign in the office like all the other parents I see that do this and ask for a hall pass and they tell me I can't go to his room anymore! What???? I said I wasn't "just walking him to his room but needed to talk to his teacher b/c he had been absent and sick for awhile." The SECRETARY looked at me and said "it is school policy you can't go to his room and bother the teacher you'll have to e-mail her or send a note!" I then (pregnant and very emotional) looked at her and said "that is the most ridiculous rule...she has no email or way of contacting her before this morning." SORRY CRAZY PREGNANT WOMAN ---- she was thinking I know! So she handed me a piece of paper and ignored me from there.
I sat in the office trying so hard not to cry in front of Ian - he was a big boy though - he didn't get upset and took my pitiful note and walked down the hall to class. I sat and watched him like I promised and then HE comes up -the principal! I mustered up the confidence and looked at him explaining my dismay that I couldn't even talk to Ian's teacher when he had been out sick and she had called me but left no contact number last week. He went on to tell me how it was to "PROTECT THE CHILDREN FROM GETTING HURT IF THE TEACHER WAS IGNORING THEM TO TALK TO ME." I responded that there was a teacher's ass. in her room every morning! He ignored that fact and said "your son will be OK. You can schedule a meeting with her during her planning period later today." (Like I'm some emotional pregnant woman or something). So, I started crying and walked away from him out the door of that horrible lock down school that is trying to protect our kids from their parents! All this concern simply b/c I don't' think Ian will tell anyone if he feels sick again - he didn't last week and when I picked him up he threw up at home and slept all afternoon - I did go over and over with him to tell the teacher if he felt sick this time. Why does he seem so much smaller then Eli when he started school? God help me this year! P.S. NOT ALL SCHOOLS ARE LIKE THIS - I KNOW FROM EXPERIENCE OF MY OTHER CHILD!!!!!
