Can I get some advice on a situation with a staff member?

I am in an R.T.F right now and there’s this staff that really irritates me.He is one of the midnight staff,and whenever I get up to go to the bathroom or something he yells at me and gets in my face,and it aint like im not asking.One night I was up six times throwing up and every time I would come out he would yell at me and tell me to get back in bed.I dont understand what I ever did.What should I do?Should I talk to the boss or what should I do?
