Is my friend toxic??

I started to notice that my “friend” has always been super competitive with me, and just me. She doesn’t exhibit this kind of behavior with any of my other friends (at least I haven’t noticed). For example, I got a good grade on a test and she responded by saying how she got a higher grade and stuck out her tongue like some child (she’s a senior in high school). Then, she brought up a time I quit a sport because I didn’t like it as much as I used to and it wasn’t for me. She brought it up to our group of friends by saying that I was a quitter and how I just quit the sport. And when we were young I invited her over to my house for a birthday sleepover and she wouldn’t stop saying how my house was broken (a lock didn’t work for a door it was weird asf). I don’t know but lately it has just been so belittling when I’m around her and I just want it to stop. What do I do about this situation?
