how do i keep believing even when things aren’t working out

so i’ve been trying to revise a situation around a job that is extremely important to me. i’ve been doing it for more than a week; telling myself nonstop that everything is okay, i have what i want, etc; i haven’t even complained to a SINGLE person which is really hard for me. i’ve been affirming and ranting and really believing but things still haven’t changed. how am i supposed to believe when i still don’t have what i want? how do i know it’ll happen??
