No is Ok

"Many Mormon women do not have clear boundaries for themselves. They feel a sense of confusion about who they are, because many competing voices lay claim to them and they try to accommodate them all. For example, when I became a member of the Relief Society general presidency, I was appalled at how many women were tormented by guilt about their responsibilities as mothers. They seemed unable to see a boundary between themselves and their children. If a child deviated from what was expected, it became a burden that the mother bore. . . .

It is a strength for women to be able to cross their own boundaries easily when they are meeting the needs of their children and serving others, but it is a great disadvantage when they feel every call for service as an imperative which they are obligated to meet. Remember, a boundary has “yes” on one side and “no” on the other. A woman who never feels that she can say “no” is lacking an important element of personal identity and, hence, personal safety.”
