Honestly the stinging won't go away. Its due to the chlorine reacting to the impurities in the pool. But if you really want to, you have to get used to it.
Just keep your head in the water and try to practice. It will take some time and your eyes may get super red. Make sure you arent tired otherwise it just irritates your eyes more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
