How do I cope at school?

I haven't been in a traditional public school sense 7th grade, I finally joined High School. My teachers (IEP, Case Manager, Social Worker, etc) are all very accommodating for me, it's just that my typical coping mechanisms aren't a thing I can do readily. Normally I would take a break, go into a empty room, etc (Basically isolate myself for awhile.) But this isn't possible all the time, and my teachers aren't exactly happy with this (It results in me leaving class a lot.) So to avoid confrontation I often will just completely dissociate myself from the class and lay my head down, or avoid going to the class entirely and hide in the bathroom. A big coping mechanism for me was listening to music on my phone, but I recently lost my phone. I'm sort of at a lost for what to do when I get my anxiety attacks, so I'd like to know some other peoples coping skills or advice. Please no deep breathing, imagine a happy place, etc. Those don't work for me.

for me I'd have to remove myself and have some time on my own to calm down, and it sounds like that has worked for you in the past also, why can't the high school be okay with what worked for you in the past?

Honestly it seems their only 'justification' is that they don't want me to miss class (The material being taught in class) But I can rebuttal that with the fact that with my modified classes and schedule all but one class (Spanish) I wouldn't need to be in the classroom at all if I didn't want to be, because literally every assignment is out of the textbook. I honestly can't get a real concrete reason for why I can't simply go to a room and take just a 10 minute break, it's not as if there isn't a room that's accessible to me (and it's not a issue with me being left alone.)

I've pressed on the matter multiple times, but I'm just met with "Go to class, you're fine." And I'm really not a confrontational person so I don't want to have to make a scene and get my mom involved to advocate for me, so I'm sorta stuck.

maybe they've decided that it's more helpful for you to try rise above it whilst in the classroom, which they probably think you have the resilience to do that - so maybe they do have your best interests at heart even though it must feel like a punishment to you.

Think and question. Question all- authority, material, and administration alike. Especially question their motives, and whether or not they act in your best interest.

Having a student regularly walk in and out of the classroom-- walking down the aisle, opening and closing the door, etc-- is extremely disruptive to the professor and other students. Just like when a student arrives late: it causes everyone to pause, look at where the noise is coming from, some lose their train of thought, etc. I say this as a professor myself. Also, allowing one student to come and go as they please-- and no one else-- can be problematic because, all of a sudden, you have 30 more students who want to walk in and out and don't think it's fair if they lose participation points or get marked tardy/absent when those rules don't apply to everyone. Finally, learning from a book/online and filling out lessons really is not the same as learning in the classroom with a professor. Every study that has been conducted on the effectiveness of online learning has born this out. So there really is value in actuallu attending class! Since school is also training ground for a professional job, being able to sit through class periods and other meetings is a necessary skill to have for most jobs. If you are going to interact with the public, work answering phones/manning a desk, work in a place that has employee meetings, or just about anything else, you wi have to be able to sit in a room and manage your anxiety for certain periods of time. It's better to work on that skill now than to wait until later, when it will be harder to change. Best of luck!

If you want (need) such accomodations (= more than the school is willing to give), wouldn't it be a better idea to try and get into a Special Education school?

You're in the USA.

You have this right.

I'm in the USA and its in my accommodation plan.

You do need to make a fuss however because otherwise they think you don't really need it.

Why don't you talk to your school counselor? May be he/she can help you out.
