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.
Is obvious that majority of this gamblers are gambling for profit making and not for fun, while most people can choose to disguise themselves as those set of gamblers whose intention is to have fun with it when they're not even one. You know sometimes I still wonder why most people choose to hide their identity in something that can't even add any value to their life instead is still going to ruing ones Future sometimes it can even make ones life to become miserable.
Though sometimes is good to hide our identity but not when it has to do with gambling, because you may be undergoing some challenges in gamble maybe in terms of emotional control, and without you telling anyone about it definitely there's no way you're going to deal with it.
