You are right, when someone is stressed or their state of mind is troubled, it would be very difficult to make accurate prediction, in sports betting one can not make good prediction as long as their mind is not settled and therefore they have to be in the right frame of mind before they gamble, unlike slot games which totally depends on luck and you can gamble without any analysis and the results depends on random generator but sport is not same thing and that's what some people do not understand.
Currently there are many people who have depression and suffer a lot from stress, I say that the level of stress is normal in a person until it reaches a certain point where it becomes less toxic, and to release these things it is better to take care of certain things, sleeping well, eating healthily, if you practice a sport it is much better, these things help a lot, if we are well in that sense we can face all the challenges without stress and depression affecting us more than normal, that is what happens with some players.
I don't really understand what many people are so depressed about. This was not a thing back when the internet did not exist yet. I guess it's also because we now lack the activity and then the pandemic came too. It messed up the brains of many people, and we tend to just be in our homes with our phones or computers and talk less with people.
Anyway, it is true that we have to keep our body healthy and so do our mental state. We cannot make an analysis if we are thinking about our losses and having some rest will help a lot. I keep on saying that because I know, I tested it on myself, and I felt better after a long rest without gambling.
