WAY out my comfort zone....

I'm going on holiday with my family and my mum n dads' good friends as well as all her family, we are going to Salou and I can't wait but I am really body shy if you know what I mean.. I want to join in with everyone (all the girls) as they are all wearing bikinis and I don't feel confident enough to do so, I don't know what to 🙃where as i don't want to be the only one wearing shorts n stuff when they are wearing bikinis 😒 I am not confident enough as I have always though I am to "fat" sorry to say but everyone else is skinny and I don't want feel awkward. Should I were a bikini or not?? Really stuck 😔😬😬 I hope this has made sense lol

Asking for help...

ps the background is a mess that's why I scribbled it out lol
