Life Is Hard!!!!! ANY ADVICE?!!!!?

I would be worried too... But if you have fun, join in and don't let them leave you out, they wont. Just make jokes and have fun with them and don't let them leave you out, just keep trying. I'm sure you will get a better bond with them all, it is a good idea to go, other wise they will have jokes between each other which you wont understand. Try not to worry so much and have fun! :)
