Relationships

My best friend is constantly copying me and trying to 'one-up' me and it has gotten to the point where I don't want to be friends with her anymore?

My best friend is copying everything I do. Even down to career's, hair styles, piercings and ideas. I even told her I was going to the beach on Saturday with my cousin & I got on Twitter & she literally posted: I hope the weather is nice on Saturday, I wanna go to the beach” it’s obvious she’s in secret competition with me. We have been friends since we were 2. She’s 24 & I’m 25 now. One time I even sent her a piercing I wanted & she posted like two days later on her social media saying she’s thinking of getting one. I will be graduating as a medical assistant on the 30th & now she’s rushing to take medical assistant classes. She’s important to me but i’m starting to think it’s not healthy & it’s making me trust her less & less. It’s like she wants to see me do good but not better than her. I’m getting disgusted because now I have to be tight lipped around my own best friend. should I cut her off?
