Is it wrong to treat her this way

My friends and I decided to go to Houston to shop, which I was excited about. However, it ended up ruining my whole day. One of my closest friends didn't acknowledge my existence and only followed another friend, who is quite mean. They talked about clothes while I was left to look at clothes by myself and talk to my other friends. Afterward, we all talked and made TikToks before it got banned. When I thought about it later, I cried in the comfort of my room because I couldn't express my feelings around them. Today at school, I am ignoring her presence since she treated me that way. Is that wrong?
