I went through what you are going right now. I still have mild cases of being triggered. There is no magical solution.
Maybe it will help you calm down to know that I live in central Ukraine. Sharpnel from last few rocket strikes reached my late grandmother’s house and glass windows in my own house were dangerously close to shattering from the shockwave.
And I don’t care. A person who is actively mixed in the war cares less than you do about the situation. So why bother yourself?
You have to avoid your triggers by any means necessary. If it means throwing your TV out of the window, do it. If it means to never speak to an old friend of your ever again, delete their contacts immediately. It won’t help instantly, but it is a start that is necessary. If you were already triggered, you will just have to wait and suffer a few days before it stops. The most important thing is to never let that happen again by avoiding your triggers.
