Baby name dilemma!!!

Currently pregnant with baby number 2 which is a little girl. Me & my partner have had our hearts set on her name since the word go, (our first born little boy would have been called it if a girl). Just found out this morning that a girl I went to school with has a 6 month old baby girl with exactly the same first and middle name 😔 I really wanted her to be different and I'm torn what to do now 😩 anyway id like your opinions on whether I should change or stick...?

Eliza Rae is the name 💗
