Telling BFF

How do I tell my BFF that has been trying to conceive for 8 years that I'm pregnant. I don't know if I should be excited when I tell her or act like it's no big deal. I don't want to remind her of her struggle or cause any pain in her heart. I know the TTC can be hard and the last thing I want is to hurt her😣😭 I pray to God he answers her prayer soon bcs I know she will be an amazing mom. HELP!!!!

I am afraid I might break down when I tell her.
