look up coping mechanisms in advance. also maybe talk to camp counselors/directors and communicate your worries and mental state. bring a journal to write in (if that’s something you like). bring everything you need to feel at home. when i went to a camp i brought my sheets, blankets, huge body pillow, heating pad and eye mask to sleep there for 3 nights. getting a good nights rest can help reduce anxiety. i’m always more anxious when i’m tired. usually when i’m in a situation and i get very nervous i go to the bathroom to calm down and come back to the situation when i’m ready. i wish you the best of luck at camp and i think you’ll have lots of fun and make new friends.
