You are not alone in feeling this. There are days when I feel as though I can barely stand to exist within this reality - there is just too much self-caused & unconscious pain. I have found comfort in the knowledge that any amount of pain I am able to reduce creates a change that ripples (to use your analogy) throughout the world.
I want you to know that the work you are doing was paramount to my own understanding of self and awakening. Everything you do and share is majorly aiding in expanding the consciousness of humanity. You are helping - never forget that.
