For me it is normal specially if the amount that we lose isn't a small amount or just a couple dollars.
I usually feel like staying out or laying low after losing a good amount of money, but if it is just a couple of dollars I would still continue to play or bet.
You're right about that, when I was a novice, I had those fears, obviously because I did everything that one should do, I did it , so in view of this, I am a person who now does not feel even the slightest fear of losing, because it is as you say , I only lose a little and I do not allow myself to lose amounts that will damage my overall economy.
It is pretty much clear the amount of damage and fear with receive psychologically as gamblers is directly proportional to the amount of money we could lose or have already lost to the casino, no questions about it.
What makes things different from a gambler to others is how each one of us would react inna situation in which we find ourselves losing money and getting afraid or hurt for those outcomes.
The immediate reaction I have when comes to those situations is to logout my session and try to forget how much money I have lost in a single seat and still come to terms with the fact I won't be able to recover it.
In general, it is easier to feel afraid of losing money when one has already lost in the past and we are venturing into territory of spending money we are not supposed to gamble.
