No one can help you but yourself and that is by accepting the fact that gambling is a riskiest area to earn and win.
and also be truth to your self , because you are literally a gambler since then.
If someone wants to gamble and he already did it, there's really no help that's needed but if he wants to learn more specifically with some techniques.
They will find it out after they've incurred a lot of losses that will teach them lessons to be applied if they continue.
