School freaking sucks

I woke up with a migraine on Wednesday but my dad said I had  to at least go to school and stay till noon. I went to my first hour class, head hurting and what not. My teacher asked if I was ok and I said no, I have a headache. she them told me if I ever needed to go to the nurse to ask. after that class i went to geometry. my head hurting more than it did earlier. After that class was lunch, I texted my dad and asked if he could come pick me up. He said he would so I waited. My friend and I walked to office. I told one of the secretaries that my dad was supposed to be picking me up and she asks if I knew what time and I said no. She then lectured me about how one of my parents are supposed to call and say one of them is picking me up before hand and all that jazz. I walked out of the office and texted my dad and told him he needed to call the office. He called the office and told them that he was picking me up. I walked back to the office and when I got there the same secretary told me to sign out. I have really bad frucking anxiety and there was a bunch of sign in and out clipboards on the desk. i went to one and the secretary told me it was the other one in a tone like she legitimately wanted to call me stupid. After I signed out she then yelled at me and lectured me about how "next time" i feel like shite that I should go to the nurse and because I went to the office my absent for the rest of that afternoon was going to be unexcused which made zero sense because it would have been unexcused too. I wanted to tell her that i was nervous because of my anxiety and tell her that I didn't know where to go. I also wanted to yell at her and tell her that I was sorry that I had so many medical problems that I don't know about and can't fix till December 6th. I do not trust the school or the people at it besides my guidance counselor, my friends and like two teachers. Literally nothing they do is for the students, and don't care weather they have anxiety or other problems. they won't even do shite about bullying either. there's not really a benefit of the doubt for students and it frucking sucks.
