Some people seem to invite emotional caretaking. We can learn to refuse the invitation. We can be concerned; we can be loving, when possible; but we can place value on our own needs and feelings too. Part of recovery means learning to pay attention to, and place importance on, what we feel, want, and need, because we begin to see that there are clear, predictable, and usually undesirable consequences when we don't.
Be patient and gentle with yourself as you learn to do this. Be understanding with yourself when you slip back into the old behavior of emotional caretaking and self-neglect.
