I might just need to vent and/or get advice but I am scared to do this elsewhere. Here it goes,

so my cousin and I planned a trip and have been planning a trip. Now keep in mind my aunt and other cousin always talk shit to me and like usually bring my vibe down. so this trip me and my other cousin were gonna go just us two, but my aunt invited herself and so did my other cousin, at first it was them two and now she's inviting 4 other people. I have always hated going on vacations with them, hence the reason I didnt invite them to this trip. I am so bothered and feel like will not have a great time with them there. I've always been brought down by this aunt and honestly she and her daughter are people who only care about themselves and what they can gain from other people. Like, I might just be hurt also because they have never cared about anyone or been interested in anything going on in my life and like even more recent like they always want pus to celebrate their b-days but dont even care about mine. im normally not a person that complains like this or likes to make peoples life difficult but idk what to do. I feel so trapped now and like I wont enjoy my trip because of this. Idk what to do, I dont want to be mean but I also can never have a break from them and now that they invited themselves on this trip im dreading it even more 😭😩.
