You have to confront any fear to beat it ! There are two ways one is gradual exposure to that fear. Understanding more about your fear subject and being familar with your fear subject!
The other way is saturation exposure ie in the case of stalling stalling in every config and beyond until you no longer fear the manoeuvres!
I believe in the Second World War they had no time to teach people to swim so dumped them in a swimming pool and only pulled them out when they sank to the bottom
Most swam got over their fears and swam
