Dear Cali Chica:

It is easier for you to deal  with N than it is to deal with your sister, of  course. Feelings are more intense in regard to your sister and therefore the challenge is more difficult, more demanding and exhausting. best you do the exercise with your sister when you are as calm as can be, when it so happens that you are exceptionally calm. You may want to create a calm circumstance to make the exercise possible, maybe with a glass of wine or after a hot bath, when you are home alone.
