Hi there. I wanted to come back and see how you are doing. Hope my advice helped and I'm happy to chat any time so this can get better. :>))
Hello, how are you? So, a little information would be helpful. Do you have any diagnosis that you know of? What triggers your outbursts? I have a son that has a hard time maintaining himself at school. It helps him to have a good amount of physical activity during his week. He does a sport at school. Cross country is a good one in Fall because anyone can join, everyone is cheered on and it can keep you nice and calm during your school day. Swimming is great too. Really, anything you enjoy doing is good to do!
What proceeds the outburst? What are the triggers? Sometimes anticipating the trigger and having a plan to do instead of the outburst can be very effective for having an appropriate response. For example, if someone freaks out at the sound of the bell letting everyone know it is time to change classes, you can plan for it. You can get a vibrating watch with a timer and have it vibrate a couple of minutes before it so you are prepared. Then you can start packing up, cover your ears, etc. to help with your negative reaction. That's just an example.
But it is important to talk to your parents, teachers and counselor.
But a little more detail would be helpful. :>)))
