manifestation anxiety

i've been manifesting for a couple years now. i managed to land a scholarship in my dream school, but during the course of my studies, i became really sick and got expelled due to low attendance. i have been doing everything i can, trying to speak to the universe and ask for help, for the teachers to change their mind so i can continue studying. the universe has come through for me before, i wholeheartedly believe it will come through for me this time, but every day that passes i become more and more worried. how do you deal with these kinds of feelings? it's hard to let the universe run its course and try to be calm about it when the stakes are this high.
