There have been times especially when I was younger and in grade school that something would get me to laughing and I'd end up laughing SO hard I'd end up in tears from laughing (NOT good when in class).
Another thing that I've found therapeutic is screaming just as loud as you can for as long as you can. If you have other family members, it works GREAT IN YOUR CAR -
alone. I've only done this once and then it was just to 'try it'. I'm not a screamer or a fighter, but wanted to see how I'd feel. It was very releasing. And at the time I wasn't really stressed about anything - well not that I remember anyway. You'd not want to do this while driving or with the family around - they might call the men in the little white coats!
Just something I wanted to try. lol
