I think the problem is too obvious for most people to bother to mention.
The only way you fold in a cash game is if you suddenly realize your outside your bankroll and immediately upon folding you take your chips and either go to a game where you have at least 20 times the buy in amount in your bankroll or go home and wait until you do.
In a tournament , the only time you fold is if the difference between what you win if you win the hand, and what you win if you lose the hand is greater than ten to one, and the difference between what you win if you win and what you win if you fold and finish in the exact position your in now is less than 1.5 to one.Even then,chances are your just outside your bankroll.
Dont listen to vicious people. Dont quit , drop down to a comfortable bankroll where you know you would never fold this hand, and keep learning
