I'm 23 so haven't been on a family holiday in many years, but my parents came up with this idea last year that we should all have a big holiday together. i saved the date and turned down days of work but never heard anything so I assumed no one planned anything. Then this morning everyone started talking about the holiday on our family WhatsApp chat, it seems almost all my 5 older siblings and their partners and children are going, yet I wasn't even invited? Even my brother who acts abusively to me and my parents seems to have been invited but did not want to go. I have visited my sister and parents within the month and no one even mentioned this. Is it because I told my parents I've been feeling down recently? They don't want me to bring everyone down? I don't get it. 

I'm normally a popular member of the family and don't tend to cause drama, I make so much effort to visit all of them and none have ever visited me. I love my family to pieces and I don't want to think badly of them but I just can't help but feel abandoned. I used to have a reoccurring nightmare as a kid that they'd all drive off to go on holiday and leave me alone, now it feels real. 

Should I confront them? Just get over it as they're not obliged to include me? Or maybe I should just ask if I can tag along? Would I then feel like some kind of unwanted spare part?
