You're absolutely right, I'm impressed with your statement on the second paragraph and I believe that's one of the best advise a therapist would insist, when letting go of gambling seems difficult, the best way to handle the situation is diverting one's attention to another area for entertainment like movies, outdoor hangouts, avoiding media platforms that advertise gambling activities and most especially avoid watch sports activities for a while since it could trigger it again.
Yes, losing streak can be very stressful. but I guess by now one should be used to such as a gambler. Most of the time, we have more losses than wins. But since we play for the fun, it actually doesn't hurt much. That's why one doesn't have to be too attached with his games to avoid being depressed. Once you are stressed in gambling just take some time off. It would help you let go, so you don't have to over think it.
It baffles me when people emphasise gambling for fun as if it's always true, how many people even gamble sincerely for fun? It must be so tiny. "Gamble" as a context is about risking your money, it is not some kind of a video game we play for fun. And truly, if most people are gambling for fun, bookies can't be as rich as they are because no one gambles for fun will risk hundreds/thousands of dollars doing that, they will surely use a ridiculously low amount to wager so that it won't affect them, let alone leading to stress.
I know every gambler has a definition for gambling and it is not that gambling is fun but because of rest of mind and what many have seen, they tend to see gambling as fun. I know many people could misinterprete it in a way like it's actually fun.
Every gambler knows what actually works for them which is why we need to know gamble based on the resources we have without having the idea of getting loan or using someone else money to bet because of the urge to make huge money from gambling.
