To say that I feel you, my friend, would be an underestimation... Being a regular witness to too much evil toward animals (my current very first priority), my heart bleeds much more frequently than it laughs and experiences joy...
I cope differently, though. I don't stop crying but I feel tons of frustration reaching the level of helplessness from time to time!
Shouldn't I be highly self-aware to self-regulate in a relatively short time and fortunate enough to be surrounded by some wondrous and precious soul-friends who constantly support me emotionally, I'm pretty sure I would have already given up...
