Well adjusted human beings have an inbuilt and learned fear of stinging insects. This is normal and to be expected. Being around thousands of buzzing creatures without running for the hills takes focus. Composure in the face of potential pain takes practice. Beekeeping is a journey.
The reality is, bees rarely sting and eventually stings really does not hurt too much. You learn to push away the fear and you will gain control. Gradually all you experience is the interesting lives of the bees in your care.
