I am asking for help regarding communicating my value to my ideal client.

My ideal client is the caregiver (female) of a spouse going through cancer treatments. They are scared and angry because of the potential fear of losing their spouse, having to raise their children without a dad, in addition to all the emotional rollercoaster that comes with caring for a loved one. I would like to help them take care of their own mind first, before they can take care of their spouse’s. I am struggling with how to communicate that.
