I don’t feel safe without my phone

So before anyone comes for me, let me explain. Last summer i had a really scary experience where i was locked in a bathroom at the beach and i didn’t have my phone to call for help. That experience has traumatized me to where i don’t feel safe anywhere without my phone. My reasoning is that if the slight chance I get locked in a room or get lost i can call for help. It’s so stupid but yeah ><
