Welcome to the community here. As RT and AS have mentioned, the bushfires are horrendous and I am sure they are affecting many people.
A few years ago we moved to a rural area and I joined the local volunteer fire service for 5 years. During that time I saw how local fires and events elsewhere affected the men and women of our brigade and how the fires affected people of the community.
I would like to ask if your brigade has a support person or support team as I know our region has a team of mental health people to assist with issues and traumas.
If you don't feel comfortable contacting them, maybe you could try talking to someone at Beyond Blue on 1300 22 4636 or Life Line. People here will be supportive as well.
I'm wondering if you are feeling the effects of the fires to a greater extent due to your own personal experiences? For those who have fought fires, the reality of what is happening is so much more heightened.
I'm certainly no expert, but I know when I am depressed events take on a greater significance, and usually not in a positive way.
Please know you are more than welcome to share your thoughts and feelings here if you feel comfortable doing so.
Cheers from Dools
