i am 32 years old and over the last 12 years when i have been laughing alot i suddenly start crying really sobbing my heart out and it doesnt seem to matter who is around i cant control it but have noticed that i am trying not to laugh to much in company and that it has become a problem as i dont need to be laughing hard for it to switch too what feels like total dispair i dont feel depressed or full of dispair just tense i dont like feeling not in control and it is disturbing to me and worse for on lookers
