some advice and reassurance please

I know this isnt really the right place to post this but i really need some reassurance, support and advice. very early tommorow morning i am going away for a long weekend for a friends birthday to stay at her house abroad. however, the only person i know going (and there are quite a few) is her and i am positive nearly everyone else going knows each other. i know it sounds silly to worry so much about something but i really am. what if they completely leave me out of things etc? i really wish i could just stop worrying-does this all sound silly?? i am also worried about what to do about food there but hopefully it will be ok. i am 20 by the way! my mum is also away and i am paranoid i am going to forget something.

sorry i just needed to vent and would love some words of advice.

I would tell your friend how you feel. Let her know what's up and that you don't want to be a "3rd wheel" in a sense. About forgetting something, just start making a list now and as you remember things write them down. Works for me. Good Luck.
