Please help

I have panic attacks and something I can describe but don’t have a name for.

I didn’t have them for a while, but when I do I’m on the floor crying, screaming, and struggling to breathe. I had a minor one at school and I had to leave class. My friend had hugged me, and for some reason my body went into panic and I started crying and freaking out. I left and just sobbed in a ball in the hallway for a while.

The other thing that happens is I start to get all fluttery in my chest. And feel butterflies in my stomach, but their not good butterflies. It’s a slow build up to a panic attack kind of? And then like really quick my hands get cold and everything just becomes louder. Things that really bother me are pencil tapping, scratching, sniffing, shuffling, any noises really. It’s like I can feel the noises, and I’m so irritated, but I don’t want to talk. And I want to cry but I can’t I just get so frustrated.

And when that happens I just need control so I braid my hair, count my fingers (strange ik), fold paper quietly, and my biggest one is plan my day by the minute. I will plan by the smallest detail, like food breaks between studying.

I haven’t reached my breaking point, but I feel on the path I am on I will eventually. I need to get it under control before I start high school next year because I know it will affect friendships and school.

My mom knows about the panic attacks I’ve had at home but everything else she doesn’t.

What is happening? Any advice? Is there something wrong?
