I've recently agreed to go on a short break with some people I don't know massively well. It was arranged on a night out and seemed like a good idea, it's something I will enjoy and I like the people I am going with. The problem is that it seems to have created a huge crisis of confidence in me!! I'm laying awake worrying about them not finding me fun enough, not knowing what clothes I should wear and basically feeling that I'm not good enough, fun enough, pretty enough, thin enough etc.. Would I be unreasonable not to go?? I'm never full of confidence but usually tick along fine so this has hit me hard. For info - I'm in my 40's, married, 2 kids
