Losing is never new to anyone. However, some just tend to lose their head that they will keep on losing. And it can really get into your nerves unless you deal with it right away. If you had $1000 bankroll but only had $50 left, then maybe it is time to go, or try to push your luck and lose what is remaining. You had Kings, three of a kind, but by the river, you lost to a full house. And its a part of the game.

Your money went all to the pot and you did not get any. Money is gone, but do not lose your sense of control. Be patient and think positive. You should know better that you need to focus and pay attention to the game. If there is no other way than to stop playing, then you need to get out of the table. Do something else to divert your attention or you can contemplate about what happened and learn from it. If you like playing poker, then have fun or do not play at all.
