The beginning of your problem was when you decided to listen to what others had to say, gambling is a personal thing, meaning that it's always you and your ideas only. 20000 BDT is a lot of money and I think you should have just walked away with it instead of gambling to make more profit. Learn to have limits that you always keep to no matter the pressure. At the end of the day you were the one that lost after letting others force you
You are correct and I agree with you that if I could stop playing, then I would not lose the money which I have won and I played for the force (by speech). But if I try not to play and if I force stop playing, then the thing might be turned into a different factor. The fact may turn into force by muscle, even if it may get into a quarrel.
