I try and find out more about the issue I fear including recent stats - 'How many women my age actually die during childbirth per year'
Then I pray and commit it all the God.
Although the fear may not actually diminish, I gain the confidence to push on.
The success diminishes the fear.
I have a fear of heights, but I have gotten to a point where I can step out to a balcony in a high rise(I can't reach the edge or look down yet).
I checked and very few people have died by falling off a balcony all by themselves when sober.
I guess we continue chipping away at our fears all through life, just keep at it.
