For starters I know that it's not easy in life some people get with a snap of a finger some people almost get it then there's the ones that it takes a whole life time to get it right oh and then there's the ones that never get regardless to what.Thats why the fortunate ones roll around with no care in the world until something bad happens then reality hits them hopefully they will be able to bounce back from it.
There's nothing really that means exactly "laughing at oneself," as far as I know, but some related words are self-ridicule and self-belittlement, though these have a more negative connotation. Hope this helps.
