I Have Retinitis Pigmentosa

Hi all I am new here! I recently found out I have cataracts..which blew my mind…but today I had to see the retina specialist before surgery and I found out I have retinitis pigmentosa … I cried right then and there and was an.emotional wreck..thoughts of not seeing my kids graduate or see my grandchildren one day??
I don’t even know if I should tell my kids…this is all still sinking in…
