Help?

I’m going on a church retreat this weekend (I’m in 8th grade btw). I rlly don’t want to go. I hate going on things like this bc I get really anxious and homesick plus I won’t know many people there. My parents say this is the only one they’ll ever make me do but I still just don’t want to go. What are some things I can do to make my experience better and look on the bright side so time will pass faster?
