Food For Thought:
"Selfish people might be embarrassed by you. While they're using their time and energy almost exclusively on themselves, they see you giving time to others, and your kindness puts them in a bad light.
Maybe they'll think you're a phony, that you use your altruism to get others indebted to you so they'll then owe you a favor. Or perhaps they'll accuse you, directly or behind your back, of focusing on the needs of others so no one ever focuses on your foibles or your genuine wounds.
All of these are false accusations; yours is a genuine compassion, because you truly have a tender heart. One criticism might be more substantial, though. People might notice when you let things get out of balance and spend so much time responding to others that you neglect your own needs.
Perhaps it's true to some extent that you are more comfortable when the focus is on someone else's needs than when you and your needs are front and center, and this may be a criticism worth paying attention to."
