I accidentally sent a somewhat friend sad crying faces in response to her Instagram story featuring a pic of her kid. 😭😭😭

I don’t know what to do. Do I message her and say it was an accidental sad face response to her child? And look like some paranoid idiot who can’t social media? Do I do nothing and just let her think I hate all children and hers especially? Will I lie in bed thinking about this late at night?
