my friend is trying to decide what i wear instead of me

ok, so i'm kinda insecure abt my body and shit BUT FOR SOME REASON, my friend has the balls to annoy me with how my outfit wll prolly suck at this concert im going to. shes using the concert she forced my friend and i to go to to say how my outfit will suck just like that one, which is literally so f-ing stupid. i dint give 2 shits abt that concert, we went to please her NOT US, her. so her thinking that she can say that i looked awful in that outfit is so annoying to me. and when i confornted her abt how wut i wear shouldnt matter to her one bit, she used her insecure ass to hide herself from the grave she dug. and now idk if i wanna even go w her. so someone plz tell me im not being a bitch and my feelings are vaild lol. if any of this makes sense lmao.
