Start thinking of playing another format, Cash games are not for everyone and I personally hate them. Try single table SnGs for a while and try to rebuild your bankroll, it may take a while but Poker is all about having patience along with skill and a little luck.
I have never deposited on any site and always managed a small but playable bankroll on several sites by playing Free-rolls and then micro-stake SnGs until I win enough to play for higher stakes.
I sometimes wonder when someone says they won X amount of money
gambling on any game of chance, even horse racing or Sports betting, exactly how much it has cost them over the years. A close friend once won £10,000 from a £50 accumulator bet on football, and within 6 months he was borrowing money again.
I can say with all honesty. I have never borrowed money to play Poker, and never will if you cannot afford it. Don't play it. It is that simple!
If you have lost huge in cash games it is time to lower your stakes or find another game that suits your Bankroll.
When the fun Stops, STOP!
