Future RN grad in May in need of help

I'm looking to apply to Mt. Sinai hospital, stony brook u RN fellowship, and any other NY/LI hospitals in the region...

HOWEVER I'm having a tough time finding where to apply/who to contact. I know I'm still a student, but I'm graduating in may and having so much anxiety about gettting jobs. Any advice would be helpful
Let me google that for you
