Our First Texas Sized Bump in the Road

So, I don't know if I wrote about this before, but our new elementary has some stringent safety rules in place. Normally, I am cool with this, but when it prevents me from walking my kindergartener to her class on her second day of school in a new school in a new place, then I have a problem.
The receptionist...I shouldn't say anything because I don't have anything nice to say. She is quite the guardian of all that is proper in the school. Fiona has been having her usual problems due to steroids. I have been working with her on that, I walked her to school (and left her at the door with Buttercup) for the past two days and today I thought I could get away with not doing it because I promised to bring her McDonalds for lunch and eat with her at the special table in cafeteria. But, while I was changing this morning, the neighbor rang our doorbell with Fiona and said she found her crying. Side note to this, I get kind of sick of people acting like I am a bad mom because I make Fiona go to school and she ends up in the nurse's office with a 'stomachache' when really she was just nervous about going to school. Anyway, I got semi-dressed and walked her across the field to school. We get to the back door and she starts crying again, saying that she was nervous because she thought there was going to be a substitute today. We had talked to the counselor previously and we thought that maybe she could walk her to her classroom again. The receptionist merely said she was in a meeting. Just seeing the receptionist put me over the edge again and Fiona's crying face made me start crying too. Fiona's not to shocked by me crying, we talked about Mom's crybaby moments when she got diagnosed. The moments have become fewer and fewer, but today was just enough. We sat down in the office and the receptionist flagged down the assistant principal to 'deal with us'.
So, we talked to the assistant principal and she seemed really understanding. It's tough to explain things to someone who has never walked in your shoes. Some people are really understanding and other people see that we seem to be okay, so there's no reason for any sort of special treatment. I just want to tell people that in order for them to understand us, they need to have a child diagnosed with cancer, but I wouldn't wish that on my absolute worst enemy. That if this had happened to them, they probably couldn't get out of bed a lot of mornings, but Fiona is here, she is happy and doing 7 hours of school and if she needs someone, adult, to walk her to class, I am going to do my best to find that.
Having had cancer as a child myself, sometimes surviving the treatment is the easy thing to do. I dealt with anxiety problems and some PTSD, before I figured out what the deal was. With Fiona, if we can cure her and avoid those lasting anxiety issues, so she can put this behind her as soon as possible, that would make me happy.
I just am so frustrated and I absolutely hate, HATE crying in public. And that receptionist! She's pretty old, but she will probably retire after Fiona completes her last year at this school.
I would post a picture with this post, but y'all don't want to see my blotchy red face!
