Its stupid to gamble with what you can't handle like you said.
I have lost a  lot initally as well, and the only good that has come out of it, is that I don't waste money on dice/other gambling games. I do a little bit of sports betting and Poker , thats all.
 
After losing before over 2 BTC, I looked for threads like these https://bitcointalk.org/index.php?topic=345103.0  , and stopped gambling thereafter, It becomes an addiction if you keep continuing after losing
