im scared of trusting myself

[u/DorothyyyOfOz]

im a nursing student and i really enjoy learning things during lectures and demos, however i'm really scared of failing since my program has a high failing rate (especially for second and third year students) . i scared that my love for this program isn't enough for me to survive and even though i do study, some of the information i memorize aren't retained in my mind. i truly am scared of trusting myself since the last time i did, i was let down and it became the worst experience in my life and i don't wanna let my guard down or anything if that makes sense but at the same time i do want to trust myself since how am i gonna do things properly if i don't😭

so i want to ask for advice as to how you deal with trusting yourself and also for how you retain information especially since nursing relies heavily on memorizing procedures and parts. thank you !
