if possible make a note (incase you cant speak) sayign "please give me space" or somegthing bc i find it more stressful for people to talk to me and trying hugging/comforting me since i just need to be aklone or it gets worse

again its different for everyone, so i reccomend watching different videos on tips and see what works best for you :D, also now days there are toys, balls and stress relief items to help you calm down

OH YEAH its also VERY imporatnt to try keep your breathing steady

Ah didnt see the top comments, id reccomend: Headphones (idealy noise canceling if not play a song you really like or one that calms you down) Keepign your eyes shut pressure (may seem harmful but if needed maybe try grabing or rubbing your arms, covering your face, etc. OR use something that might be around you in the car to push/rub against your skin/clothes.) Maybe humming??
