Test anxiety

any tips to like, not be anxious. I feel like ts affecting my sleep and well-being. i don’t wanna get into the nitty gritty of it but all I’m gonna say is that i feel like i over-study and that an exam will make or break me when deep down i know that shit is not true, but i can’t help but think i have to do well because people always tell me “you end up doing good anyways” (which i don’t believe is true but whatever). I guess I just want to meet the expectations of others and also prove people wrong lmao…and then i stress at the fact that if i walk into the exam room and look at my exam and blank out b/c i did that a lot at one point in high school, which idk how it has a great effect on me considering that I’m basically going into third year. i also like wake up anxious and then I’m like “oh my god did i remember to pack my snack? I’m going to be hungry” ”did i remember to pack highlighters?” “did i remember to pack…” list sort of goes on lmao. anyways, any advice from a stranger is much appreciated. this feels weird that people will read ts which is why I’m not going to be too detailed. lol.
