Anxiety help

I know I’m probably just being an insane nutcase… but I’m all of a sudden having major anxiety over someone getting ahold of one of my child’s birthday invitations that I mailed a week or so ago that shows our address and my phone number.

It started when I got a call around 11pm and from a “no caller ID” number and when I rejected it they called again and I rejected again and that was it. I don’t typically get junk calls this late so it freaked me out and now I’m just imagining someone coming here in the middle of the night to grab her and I can’t sleep.

I just need someone to ease my mind a bit (without being mean about it please)

I know I sound crazy but I battle with anxiety and I can’t help it.
