A few nights ago I was over at a friends house having a takeaway and a few drinks with a few others. I have only known these friends around a year when our friendship group started. Prior to this I never had many friends and suffered with low self esteem and some social anxiety. I have really pushed myself out my comfort zone over the past year and forced myself to be a 'yes' person. We meet up often and I always make the effort to arrange things myself (though quite a few times I've suggested things my messages have went ignored). I thought I had been doing well and kind of 'faked it til I made it' kind of thing being social when it doesn't come naturally. I popped to the toilet while at this friends house and when I came back down I heard one of them say 'she's coming back shh' and then there was an always silence while I assume they thought of a way to quickly change the conversation. I didn't say anything, purely just because I'm not a confrontational person and as they are still quite new friends I didn't know how to approach it. I tried to pretend I never heard it but it felt a bit awkward after that.
We had been having a good night, laughing and joking and I've been wracking my brains trying to think about what they were saying. I've been quite down about it today and feel like despite my efforts I'm usually the one of a group who is a bit left behind, in my early 20's I had a group of friends who wouldn't treat me very well, often all would meet up without asking me and one even stole money from me on a night out, after I realised it was toxic I stopped bothering with them and rarely socialised as I didn't have anyone else or any hobbies at the time to meet people. This isn't a pity party, just hoping to get advice. Should I just forget about this, get over it and pretend I never heard it? Or try and approach it somehow?
