Do I have the right to be upset wit my friend?

So I have 2 friends we work together everyday and we are supposed to be best friends and now lockdown has been restricted we are allowed to go out together. We all planned to go to the beach for a bbq and drinks we planned it for a certain day time and everything yet the day before our friend who is driving texted us saying she has invited 2 other girls to go instead and only one of us can go now as there is only 1 seat left so fight it out between us. Basically putting me and my other friend against each other so I was the bigger person I said my other friend can go so she got ready and everything and last minute she texted her saying she cant go anymore because she has decided to take another one of her other friends and there is no room for her. I think it’s just selfish and horrible especially when we all planned to go together for months and the other girls she has gone with she is always Bitching about saying she hates them. All day she has been sending me pictures of them all at the beach saying she wishes her car was bigger so I could be there shesjust fake af she said we will plan something some other time but I have no intentions of ever going out with her again. Also one of the other girls she is going with is supposed to be my friend aswell and when I asked her about the beach she lied to my face saying she had no idea what i was talking about even though everyone already told me she was going and was on all the pictures. Am I over reacting by never wanting to associate with any of the again.
