My knee's give out when ever i laugh and my face i loose control sometimes its the weirdest thing .?

It is such a deep sincere laugh from within that my breath or diaphragm collapses my knee's and my face I have no control over. I have rolled my ankle fell down. Now i try too avoid really funny situations ha because i don't want to fall or something. please helpMy knee's give out when ever i laugh and my face i loose control sometimes its the weirdest thing .?
Maybe the reason you laugh like that is a gift to other people - you bring the gift of laughter to them. That sounds hilarous/
