While 2018 saw a slew of celebrities speaking openly about their struggles with mental health—Ariana Grande spoke of her anxiety and PTSD on her song “Sweetener;” Chrissy Teigen took to Twitter to discuss her postpartum depression; and Jon Hamm talked of his therapy and antidepressants—there’s still a stigma attached to seeking professional help.

When something traumatic happens, people have psychological needs as well as physical ones. Mental health professionals from the University of Nevada, Las Vegas volunteered to help after the Las Vegas shooting last year, and they recently told The Conversation what good psychological first aid looks like.

Stacie Armentrout felt nauseated watching surveillance video of Stephen Paddock roaming Mandalay Bay in the days before the Oct. 1 shooting on the Strip.

Mandalay Bay hotel of Las Vegas will eliminate its 32nd floor by the end of this week, from where gunman Stephen Paddock rained bullets on ground in October last year, killing 58 and wounding more than 500 others.

The 32nd floor at Mandalay Bay, strongly associated with the Oct. 1 shooting, is going away.

Losing a parent in such a public and traumatic way can send a child into a tailspin, UNLV clinical psychologist Michelle Paul says.

When the bullets started flying on that October evening, some hit Las Vegas’ Route 91 concert stage so close to Royce Christenson that shards of aluminum landed in his hair. He saw a man go down, and the man “did not get back up.” He applied pressure to a bullet wound in a woman’s leg.

Oct. 8, 10:03 p.m. “Sweet dreams beautiful girls,” Anna Kopp wrote in a Facebook message to four women with whom she fled the storm of bullets that rained down over the Route 91 Harvest festival a week earlier.
