In my opinion, the first sign of gambling addiction is that the person regrets the lost money but again and again visits the gaming platform in the hope that today he is lucky and winnings will contribute to changing his life for the better. He comes to the casino not to enjoy the game, but for the result, which often turns out to be not what he expects.
The manifestation of stress, depression, gambling with credit money, etc. is already a neglected degree of gambling addiction which is very difficult to cope with alone.
If you are chasing the loss often and you do not accept your losses then you are a gambling addict.
Depression and stress are obvious to develop in gamblers if they are losing more than winning and there is no money management plan in their approach.
