is it possible to be too competitive, and if so, how do i fix it??

for context, i am in nursing school, and i can't stop seeing everyone as someone i'm competing against.

i hate helping people study, because i don't want anyone to do as good as me. i feel like this with EVERYTHING in my life, and its so draining. i love my friends & of course i want them all to succeed, but i can't help from making everything into a silent competition & i don't know how to stop. for example, my roommate has struggled a lot with school, and even though it's hard to admit, i honestly like seeing her struggle. she's my best friend & i love her to death, but it just makes me feel good knowing i'm doing so much better than her, and i hate the idea of having to help her get to the point i'm at now.

i dont know if this makes me a psychopath or if i should talk to someone about this... is this normal? how would you guys deal with this??
