Steve Reveles, an 18-year-old from Oregon who tweeted these exact feelings on Sunday, told BuzzFeed News these anxious thoughts are “just getting worse” for him.

“I’ve kinda had this fear for a while but it’s just getting worse because they’re happening more frequently and who knows where the next mass shooting is going to happen or how many are going to happen?” said Reveles. “Am I safe anywhere?”

Other Americans are worried they need to have an escape plan anytime they’re in a public space.

Jes Karakashian, 43, of Rochester, New York, told BuzzFeed News she sees a therapist for this type of fear. She wants to keep speaking about it so that “others… know they’re not overreacting,” she said.
