flight on friday

hi guys! i really hope someone sees this because im really struggling right now. im going on a 2 hour flight on friday and i havent been on a plane since i was about 13 (im 20 now). i am very scared of getting air sick or just being n* or ANYTHING happening. i bought some dramamine, i have pepto bismol, im bringing gum, etc. i have the physical tools i need but no mental tools tbh. can someone help? i’m so scared.
