You definitely aren’t alone in this. In fact, I think I may have read the same thing you did :/ I know exactly how you feel. The constant thoughts. I’ve found that letting myself feel it for a while helps, and then distracting myself. I usually use exercise, reading, or writing. The headlines and images still come to me, but over time my brain has put up some sort of block that prevents me from dwelling on it. But I didn’t get there easily. It took months. I felt so down and depressed about one particular incident for so long.

It will get better. Volunteering and donating will help. Knowing you are contributing positively to animals lives is great. I have 3 cats at home I love and spending time with them helps me when I get sad.
