I get that all the time, what helps is breathing exercises and eating lemons drops (sour candy reroutes anxiety pathways in the brain to make you calmer.) Also a medication that helps is propranolol if you don't want to commit to an antidepressant. Hope this helps <3

I used to take a frozen water bottle with me to school every single day, if I started getting anxious in class I would breath and try to talk myself down from it. I would bounce my legs to calm me down and if none of that worked, I pulled my frozen water bottle out and held it to my neck. It’s always cold enough to shock or refresh my system. If none of that worked, I would go to the bathroom and breath or ask to go to the nurse and get an ice pack to cool down some more :)

i personally listen to music as much as i possibly can and having something like gum or a mint in my mouth. fidget toys could help too :)

stim toys, mints, weed is there something specific you’re worried about that could be addressed in some way?
