Members of the Calgary Fire Department and others are set to say goodbye to Capt. Barry “Bear” Dawson on Friday.

The 47-year-old’s sudden death is yet another example of the dire consequences for first responders struggling with mental health issues.

“He was so compassionate and understanding and always reaching out,” Melissa Murray, Dawson’s fiancee said.

“Barry was a very respected, well-liked person, nobody would have guessed because he was just so happy.”

Dawson was a musician and outdoor enthusiast who loved biking and skiing.

He also worked for the Calgary Fire Department for 17 years. Murray said Dawson would often talk to his crew following difficult calls.

“His approach with his colleagues and his patients was second to none,” she said. Tweet This

“He told me he would pull over to the side of the road and he would say, ‘OK guys, let’s talk.'”

But in August, something shifted for the man known for his passion for life.

Dawson was facing a promotion and working on home renovations and Murray noticed him becoming more anxious and easily stressed. They decided to take a sunny vacation, but shortly after their arrival, Murray said something inside Dawson switched.

“He woke up, after going to bed completely normal, terrified and shaking and sweating and pacing, and his eyes looked horrified,” she said.

Murray said he wouldn’t tell her what was wrong and that his mental health drastically declined over the course of four weeks.

“He stopped participating in any of his regular activities, he stopped playing music to the extent that he was just wearing his headphones with no music on.”

Murray — a paramedic — decided it was time that Dawson seek treatment from a doctor. But she said they would only treat him for insomnia and she couldn’t persuade Dawson to seek help from the Calgary Fire Department.

“There is still unfortunately a stigma and I wonder if he was hesitant to pursue the help that he needed for fear of how people would perceive their captain,” she said. Tweet This

Barry took his own life on Nov. 11.

“I just wish that he could have held on, I wish that he knew that my love was stronger than his pain,” Murray said.

“There’s no doubt in my mind that there are many of our colleagues in EMS and police and fire that are struggling with mental health issues and anxiety. I just plead with them to set aside reputation and fears and the ‘suck it up factor,’ and get help,” she said.

“I have a whole lot of fight in me, that I wish I could have fought harder. I could have fought harder.”
