my grandma and mother would say this and i need help how to say it and spell it.

my grandma and mother would saying something that they said meant " jesus help you child". i catch myself saying it too, but i know im not getting it right. I was wondering if anyone can help with it. it wasnt as long as google translate has it. my grandmother also likely spoke Buffalo Polish (Buffalo NY, many immigrants moved there and formed their own accent/dialect.) 'jesus ko____' assuming the 'ko' start is right. i heard it a lot, but it was usually quiet and under their breath, lol.

Maybe "Jezus kochany!" (also "Jezu kochany") literally both mean "Dear Jesus!"

Put it in google translate for the pronunciation.
