For me it helps to turn it over to a higher power. I have convinced myself that the pain and suffering the animals go through is to teach us a lesson or test our hearts and maybe even some of the animals I have helped are angels sent to see where I am at for example if in a hurry do I still stop to help the turtle out of the road or drive the injured squirrel to a rescue center? I read once that people from 9/11 felt God with them, holding their hand, listening to their prayers, comforting them and I believe in my heart He does the same for every single one of His beloved animals. It is us that suffer when we see cruelty so my first instinct to hurt the person causing it must be overruled with peace and prayer that they will have a change of heart one day if I lead by example. I have to intentionally replace horrific images, which I try to avoid because I already know of their existance but sometimes still encounter, with thoughts of animals myself and other animal lovers have helped. Reciting the verse about God being a just God and leaving the vengence to him also helps alot, there is nothing I can do that compares with that!
I completely relate to this post. I think what helps for me is realizing that I AM enough. I'm not discouraging donating money to organizations against animal cruelty or participating in activist events. I just continue to remind myself that I vote with my dollar. I spend a little extra on cruelty-free shampoo and conditioner, for example. I'm doing everything I can to put the meat industry out of business simply by NOT purchasing meat. I feed all of my non-vegan family members and friends delicious meals to show them that being vegan is delicious and that animal products aren't necessary. Furthermore, I take comfort in the fact that when my children are born, I will raise them to love animals instead of eat them. The cruelty is utterly depressing and I often feel guilty for turning a blind eye. I take comfort in the fact that I'm making a statement with my life, though.That's powerful.
I have the same issues when I see pig trucks. I am very involved in dog rescue. It's really bad to say but the more you do, the more bad stuff you see, but I feel better knowing that I am doing something. When I see something that bothers me, I normally think about it alot as the bad things tend to stick with me. On a happier note, we just moved out to the country with our dogs and will be getting chickens,hopefully a goat, mini horse, and some piggies in the future. All rescued of course. It may make you feel better to do something, whether it be volunteer. But the organizations do need your support, so see if you can google their mailing address or phone number. Some places have these and you can mail them a check?
