The key phrase in your post seemed to me, where you talk about the fear of losing about a large bet amount, if this causes fear, then it would be reasonable to avoid this combination, just do not make large bets that you are afraid of losing. You should always strive for comfort, everyone can start listening to themselves, when we do something that we do not like you will feel internal resistance, listen to yourself and do not do what you do not like or if you are afraid of the consequences. No need to chase one big win, break the bet into many small bets and reduce the risk of losing everything in one bet.
For the sake of not losing your mind, it will be better to just have a mind of your own. When you are no longer comfortable, it will be better to just allow it, Gambling is not for everyone, and it is good to take risks, but there is a limit to everything, and if you are betting, you dont need to bet at all if you are scared of the money you are going to lose because in life you use money to get money, and it depends. To be a gambler, you have to be ready to lose money, and if those that will encourage you to take another step, life is risk, so bet what you can lose, according to some people.
There are many reasons to enjoy gambling. There are some gamblers that you will see are doing very well despite the amount of money they are losing. They understand so much and didn't duel in the past. When you think too much about the past, you will not succeed because all your target will be on how to recover what you have lost, so this is why growth is important in this aspect.
