Once you get chickenpox, then only after a long period you will get it again. this is because your immune system knows how to respond to the pathogen the second time. so even though you get it, it won't as severe as the first time.

Once I got into a huge fight with my brother. He was refusing to listen to my point of view, so I got very frustrated. I ended up storming off to my room and hurting myself. Instead, I should have tried to talk it out with my brother, or tell a parent.
Hope that helps :)
