Thanks, Marjorie, Aude and John.
That's true about so-called emergencies. The lives of some whom I've known are high drama on a daily basis. Included in this are those who absolutely require professional help due to diverse abuse issues. The correctly stated matter of self-centeredness and, in addition, frequent displays of petulant behaviors merely add to the delightful mix.
My former brand of Christianity had me a ready but not always so willing doormat. A strong element of coercion and, yes, emotional blackmail have been involved.
I am learning to say no, but it hurts both ways. My survival and attention to personal needs, however selfish I have been made to feel when "neglecting" certain demanding individuals, are nonetheless important.
Gratefully,
