work problems

I literally started my new job October 4th. I'm the new girl. I absolutely love my job but last night was absolutely horrible. I don't think I've ever been hurt so badly. I was being belittled and bullied all night by a woman who has high seniority. In front of a bunch of people that just laughed. Long story short she wouldn't rotate like we were supposed too, she wouldn't let anyone take her spot for the entire 8 hour shift. When I tried to take her spot she refused and yelled at me in front of 6 other people saying I had to take the guy across from hers spot. So I just shit my trap and did. I confided in someone that I was frustrated because it through off my night. That person than told her that I was "talking about her" and she confronted me again yelling at me saying "next time other things will happen". Idk what exactly she means by that. I'm just really upset and hurt because I very genuinely like my job but this lady is so rude and completely out of line. I guess what I'm wondering is do you think I should go to hr? I don't want to be the whinely little bitch that goes to the office for help, but I also don't want to be pushed around, some help. 😞😞😞😞
