As a gambler it's important to know how to control your emotions and discipline yourself, not just in the aspect of gambling but in every other area of life. Emotional instability caused by depression can lead to a whole lot of regretful actions. Gambling when you are having mixed emotions can cloud your judgment and also affect the decisions you make, at that point you wouldn't mind if you are losing and you can keep going till you have nothing left all under the excuse of chasing your losses. I have had some experiences where I decided to gamble when I was emotionally down and I regretted my actions. Some cases are actually a psychological issue where gamblers knowingly try to make themselves sad by ruining their financial life consciously, this is rare but it happens. Don't engage in gambling when you are depressed, if you are looking for a distraction try to do something productive instead.
I highly agree, people who are depressed are not psychologically and emotionally stable. Engaging in gambling while depressed can highly trigger an addiction. A person who is depressed thinks that he is trying to escape his situation but unknowingly trapping himself into addiction.
Besides the mind being numb because of depression, a person may not have a feeling of control over his decision and may possibly gamble more than what he can afford to lose and may not feel the lost until later when he recollected his thoughts. This is the same thing as engaging in gambling while drunk or intoxicated, except that being depressed has a consequence of relying to gambling more to escape thus resulting to continuous gambling that may lead to gambling addiction.
How about the concept considers gambling for fun and entertainment i think we have been discuss about this plenty although this is not generally but for some people by doing a gamble it can makes their level of depression decreases so usually these people are not aiming to win from gambling because what they want are enjoyed their gambling activities so losing a few dollars in gambling is fine for these people as long as they can forget about their problems when gambling
I think gambling does not decrease depression. It is only a short-term distraction but in reality the depression is still there. Gambling may relieve stress but stress and depression are two different thing. One need to fix the source of depression in order to decrease it, while gambling can't fix the source of depresion, worst it can even make depression even worse due to financial losses that can lead to financial ruins which will add more burden to the person resulting to a deeper feeling of guilt and feeling of uselessnes.
