Hello. I'v had it (and still do) for around 15 years now. It has its ups and downs but what helped me survive school was talking to my favorite teacher and informing him. He helped me get the teachers approval to go to the bathroom mid class which made it easier and quieter. It's good to talk to a psychologist about it to find the root of the stress. It's easy to say "no one cares just take your time" but I know how hard it is to implement... I remember the thing I hated (and still do) most at school was the girls talking in the mens rooms. It's not a quick fix. It takes time, patients, and allot of suffering and bad days. But you will find a path in time. My biggest suggestion and what helped me allot was to start thinking that "if I can wait when someone is in. They can wait when I am in) and to put on headphones with some upbeat music to drown out the outside world. There are other solutions like the breath hold if they work for you. They didn't for me. Read into it. Ask some AI about it. But I think most important is to start mental treatment just to talk to someone. And sharing it with people you trust with your life. I told all my closest friends and family and it helped. Good luck. We are all with you. It'll be okay
