My friends keep making me laugh so much, and my bladder is weak so I keep wetting

myself. What can I do? I would like to know if there's anything I can do without going to the doctor about this. I'm a teenager so this is such an embarrassing problem, and it gets really hard to cover up at school and when I go out with my friends. I obviously don't want to change my friends just because they make me laugh to much. Even if I do go to the toilet before I go out, it still happens. Is there a quick method that's easy to do and doesn't require me going to the doctor?
