urgh i’m having a really really hard time managing my anxiety right now. i’m going on a 7 hour road trip to get our puppy ( our 13 year old german shepherd passed away recently &amp; getting another puppy to raise was the best idea for our family )with my family in a week &amp; i love road trips / car rides but for some reason all i can think about are the ‘ what if’s ? ‘ what if i throw up ( i have emetophobia ) what if i have a panic attack , what if i need to take more bathroom breaks then everyone else, the list goes on. 
i packed my car bag with every possible thing i would need to make me feel comfortable ( snacks, books, fidget games, colouring books, etc ) yet my deliberating anxiety is telling me not to go when i really really want to.
my family knows about my anxiety but i haven’t brought up the topic in a while , i have weird tics that i sometimes do when i’m anxious &amp; being in a car if i were to be anxious just scares me &amp; makes me even more anxious. 
any tips or literally anything that can help my anxiety &amp; calm me down would very much be appreciated !!!
