Me and my friends have booked a holiday, I had never fully decided if I wanted to go or not because they were leaving me out, I felt like I couldn’t be myself around them, I felt I was being judged all of the time. I thought that we would become closer in time, needless to say this hasn’t happened. My best friend is not interested in how I am, she’s basically left me for another friend. So I’m going to cancel the holiday. The only issue is that I don’t know what to say to them, I can’t say I feel left out because they’ll start arguments with me and I can’t mentally handle another argument, plus I’ll end up with no one and feel even more alone.

What reason can I give them to why I don’t want to go on holiday?
