this is a normal thing to be felt as a gambler. it would be much better if you will have the thought of quitting upon losing, because some people are becoming more eager to win which yields to gambling addiction. In order to avoid such thing to occur, keep in mind the purpose of gambling. Gambling is just an activity which is meant for entertainment. Disregard the expectations of becoming rich through gambling because only some are lucky enough to have huge winnings. This will push you away to gamble that much and to not feel stressed when you are losing because at the same time, your losses will not be that much since you are not gambling that much, as simple as that.
