My mom is ENFJ and she has this problem a lot. She will do anything for anyone, and eventually people (including us, her children) start taking her for granted. She is always exhausted because she's so damn self-sacrificing. She needs to learn to say, "No" sometimes. But it's hard to do that...I know. I'm sorry you ENFJs have this problem... From now on I'll make sure to let all of you know how much I appreciate you, through words and actions.
