My apologies for the late reply. You should probably tell the older people around the camp about your anxiety involving the water to avoid trouble. I don’t want you being in any danger because of that- And I know you’ll do great bro fist- Remember not to push yourself though and take time away when you need it. Not.. that I have much experience with the crowd situation but try not to overthink it too much before you get there, maybe try keeping your mind on what you’re looking forward to at camp.
