Sorry to hear that your daughter is battling high blood pressure Kathleen! I know it's frustrating when we young daughters don't want to listen to our parents. I'm sure it's hard for her to realize how serious this can be and especially because I'm going to bet she is not really having any symptoms. It's harder when you have a problem but it doesn't really show it's symptoms so you go about life acting as if there is nothing wrong with you.
I will keep both her and you in my prayers and I hope that she will find it in herself to realize this is something to not mess around with.
Love and Prayers!
